Answers

Answer:

sqrt (2) * sqrt(45) + sqrt (2) * sqrt (80)

45 = 9 *5 "9" is a perfect square so

sqrt (45) = 3 * sqrt (5) * sqrt (2)

sqrt (2) * sqrt (80)

80 = 16 * 5 "16" is a perfect square so

sqrt (2) * sqrt (80) = sqrt (2) * 4 * sqrt(5)

Adding both answers we get

3 * sqrt (5) * sqrt (2) = 3 * sqrt(10)

PLUS

4 * sqrt (10)

which equals

7 * sqrt (10)

Find the measure for angle A.

A. 75
B. 60
C. 30
D. 38

Answers

180-90=90 (right angle is 90; all angles in triangle add to 180)
So the last two add up to 90
x+37+x+67=180 SPOE and CLT
-37 -67 -37
-67
2x=76
———-
2
X=38

∠A = 30°

180 = 90 + x + 37 + x + 67
180 = 194 + 2x
180 - 194 = 2x
-14 = 2x
-14/2 = 2x/2
-7 = x

substitute x for (-7)
∠A = x + 37
∠A = (-7) + 37
∠A = 30°

Answer:212.4

Step-by-step explanation:

Opposite/hypotenuse

Sin23=83/x

Multiply x to both sides to cancel out the x under 83

You get xsin23=83

Then divide sin23 to both sides

X=83/sin23

X=212.4

Find the discriminant and determine the number of real roots for each equation. Show steps.

-9x^2 + x - 7 = 0

Answers

Answer:

0 real roots

Step-by-step explanation:

Given a quadratic equation in standard form

ax² + bx + c = 0 ( a ≠ 0 )

Then the discriminant is

Δ = b² - 4ac

• If b² - 4ac > 0 then 2 real and distinct roots

• If b² - 4ac = 0 then 2 real and equal roots

• If b² - 4ac < 0 then the roots are not real

- 9x² + x - 7 = 0 ← is in standard form

with a = - 9, b = 1, c = - 7 , then

b² - 4ac = 1² - (4 × - 9 × - 7) = 1 - 252 = - 251

Since b² - 4ac < 0 then the equation has no real roots

What is a triangle?

A triangle is a 2-D figure with three sides and three angles.

The sum of the angles is 180 degrees.

We can have an obtuse triangle, an acute triangle, or a right triangle.

We have,

The reason for this order is that an equilateral triangle has all three sides equal in length, while an isosceles triangle has two sides equal in length and one side different.

A scalene triangle has all three sides of different lengths.

Since all three sides of an equilateral triangle are equal, it has the smallest perimeter of the three types of triangles.

The isosceles triangle has two sides equal, so its perimeter will be greater than that of an equilateral triangle, but less than that of a scalene triangle.

Finally, the scalene triangle has three sides of different lengths, so it will have the largest perimeter of the three types of triangles.

Thus,

The triangles with equal sides from least to greatest

Equilateral, Isosceles, Scalene.
