Answer:

The measure of angle x is 68°

Step-by-step explanation:

The isosceles triangle has two sides equal, the angle between these two sides is called the vertex angle, the other two angles are called the base angles and they are equal in measures

In the given figure

∵ An isosceles Δ has a vertex angle of measure 68°

∴ The other two angles are equal in measure ⇒ base angles

→ The sum of the measures of the interior angles of a triangle is 180°

∴ The sum of the measures of the base angles = 180° - 68°

∴ The sum of the measures of the base angles = 112°

→ Divide their sum by 2 to find the measure of each angle

∵ The measure of each base angle = 112° ÷ 2

∴ The measure of each base angle = 56°

∵ There are two intersected segments

∴ There is a pair of vertically opposite angles

∵ The other isosceles Δ has a vertex angle of measure x

∵ A base angle of the 1st Δ and a base angle of the 2nd Δ are vertically

   opposite angles

∴ They are equal in measure

∴ The measure of the base angle of the 2nd Δ = 56°

∴ The two base angles are equal in measure

∴ The measure of each base angle is 56°

→ The sum of the measures of the interior angles of a triangle is 180°

∵ 56° + 56° + x = 180°

∴ 112° + x = 180°

→ Subtract 112 from both sides

∴ x = 68

∴ The measure of angle x is 68°

Answer:

a=-2 and b=10/3

Step-by-step explanation:

Given that [tex]2i-2+i-\frac{2i}{3}+i=a+bi[/tex].

[tex]\Rightarrow -2+2i+i-\frac{2i}{3}+i=a+bi \\\\\Rightarrow -2+(2+1-2/3+1)i=a+bi \\\\\Rightarrow -2+\frac{10}{3}i=a+bi[/tex]

On comparing the real and imaginary parts, we have

a=-2 and b=10/3.

Answer:

C. [tex]\frac{12}{7}[/tex]

Step-by-step explanation:

To find the slope when you know two points, use this formula:

M = y₂ - y₁ ÷ x₂ - x₁

M = (4 - (-8)) ÷ (0 - (-7))

M = 12 ÷ 7

M = [tex]\frac{12}{7}[/tex]

Answer:

y = 3x - 7

Step-by-step explanation:

Slope-intercept form:

y = mx + b

Where:

y is the y value.

m is the slope.

x is the x value.

And b is the y-intercept.

First, you want to find your slope. To do this, you can either use the slope formula to find the slope, or just count on the picture:

m = rise/run

m = 3/1

m = 3

With the slope formula, you first need to choose two points.

I chose:

(2, -1) and (3, 2)

Slope formula:

m = (y2 - y1) / (x2 - x1) {It doesn't matter which point you choose to be x2 and x1, just be consistent when you plug it into the formula}

m = (2 - (-1)) / (3 - 2)

m = 3/1

m = 3

Now that you have your slope, all you need is your y-intercept. To find your y-intercept, you can either look at the graph (again) to see where the line intersects with the y-axis, or you can solve it algebraically:

y-int = -7

To solve algebraically, choose a random point on the line and plug it into what you have for your equation so far and then solve for b.

I chose:

(2, -1)

y = 3x + b

-1 = 3(2) + b

-1 = 6 + b

-1 - 6 = b

b = -7

Now you have your final answer:

y = 3x - 7

Answer:

13 units

Step-by-step explanation:

Giveb that :

Perimeter = 5/2 + 8/2 + 5/2 + 8/2

Hence, sum of the perimeter will be ;

The L. C. M of the denominator = 2

(5 + 8 + 5 + 8) / 2

= 26 / 2

= 13 units

Hence, the perimeter of the rectangle is 13 units

Answer:

Number 4, the last one

Step-by-step explanation:

The answer is the first choice.

For every odd-degree polynomial function,

When x approaches positive infinity, y approaches positive infinity.

When x approaches negative infinity, y approaches negative infinity.

As shown in the graph, substituting x into any numbers that are greater than 3 and you'll see how the graph heads toward y-value infinitely.

Answer:

229.5[tex]cm^{2}[/tex]

Step-by-step explanation:

In order to calculate the area of the arrow we need to calculate the area of the body of the arrow, and then the head of the arrow. The body of the arrow is a rectangle meaning that the area (Ar) can be calculated by multiplying the length by the height like so...

Ar = l * h

Ar = 11cm * 12cm

Ar = 132 [tex]cm^{2}[/tex]

Now we need to find the area of the head of the arrow, which is a triangle and therefore we can use the formula for the area of a triangle (At) which is height times base divided by 2...

At = [tex]\frac{h * b}{2}[/tex]

At = [tex]\frac{15cm * 13cm}{2}[/tex]

At = [tex]\frac{195cm^{2} }{2}[/tex]

At = 97.5[tex]cm^{2}[/tex]

Now we simply add both areas together to calculate the total area of the arrow...

132[tex]cm^{2}[/tex] + 97.5[tex]cm^{2}[/tex] = 229.5[tex]cm^{2}[/tex]

Answer:

edfghjkoijuhgyfdsdfghjkl

Step-by-step explanation:

Step-by-step explanation:

Open the brackets

px - pq = x

Add pq to both sides.

px = x + pq

Subtract x from both sides.

px - x = pq

x (p - 1) = pq

Divide both sides by (p - 1)

x = pq/(p-1)

Answer:

[tex]x = 10[/tex]

Step-by-step explanation:

Given

$x per adult

$8 per student

Population:

[tex]Students = 1[/tex]

[tex]Adults = 4[/tex]

[tex]Total = \$48[/tex]

Required

Determine the equation and solve for x

The system can be analyzed as thus:

The cost for 4 adults is: 4 * x

The cost for 1 students is: 8 * 1

Total Amount is: 48

From the analysis above, the equation is:

[tex]4 * x + 8 * 1 = 48[/tex]

[tex]4 x + 8 = 48[/tex]

Subtract 8 from both sides

[tex]4 x + 8 -8= 48 - 8[/tex]

[tex]4 x= 40[/tex]

Solve for x

[tex]x = 40/4[/tex]

[tex]x = 10[/tex]

Answer:

Step-by-step explanation:

Using the formula for calculating speed;

Speed = Distance/Time

Given

Speed = 3/24 miles per 3 hours

Required

Distance travelled in an hour

3/24 miles = 3 hours

x = 1 hour

Cross multiply;

3 * x = 3/24 * 1

3x = 3/24

Cross multiply;

3x * 24 = 3

72x = 3

x = 3/72

x = 1/24

Hence the distance travelled each hour is 1/24 miles
