Answer:

Sum of interior angles of a triangle = 180°

Sine rule to find side lengths:

[tex]\dfrac{a}{\sin A}=\dfrac{b}{\sin B}=\dfrac{c}{\sin C}[/tex]

----------------------------------------------------------------------

Question 1a

Given: A = 40°, B = 20°, a = 2

40° + 20° + C = 180°

⇒ C = 120°

[tex]\dfrac{2}{\sin 40}=\dfrac{b}{\sin 20}=\dfrac{c}{\sin 120}[/tex]

[tex]\implies b=\sin20 \cdot\dfrac{2}{\sin 40}=1.064177772...[/tex]

[tex]\implies c=\sin 120 \cdot \dfrac{2}{\sin 40}=2.694592711...[/tex]

----------------------------------------------------------------------

Question 2b

Given: A = 50°, C = 20°, a = 3

50° + 20° + B = 180°

⇒ B = 110°

[tex]\dfrac{3}{\sin 50}=\dfrac{b}{\sin 110}=\dfrac{c}{\sin 20}[/tex]

[tex]\implies b=\sin 110 \cdot\dfrac{3}{\sin 50}=3.680044791...[/tex]

[tex]\implies c=\sin 20 \cdot\dfrac{3}{\sin 50}=1.339426765...[/tex]

----------------------------------------------------------------------

Question 3c

Given: B = 70°, C = 10°, b = 5

70° + 10° + A = 180°

⇒ A = 100°

[tex]\dfrac{a}{\sin 100}=\dfrac{5}{\sin 70}=\dfrac{c}{\sin 10}[/tex]

[tex]\implies a=\sin 100 \cdot \dfrac{5}{\sin 70}=5.240052605...[/tex]

[tex]\implies c=\sin 10 \cdot \dfrac{5}{\sin 70}=0.9239626545...[/tex]

----------------------------------------------------------------------

Question 4d

Given: A = 70°, B = 60°, c = 4

70° + 60° + C = 180°

⇒ C = 50°

[tex]\dfrac{a}{\sin 70}=\dfrac{b}{\sin 60}=\dfrac{4}{\sin 50}[/tex]

[tex]\implies a=\sin 70 \cdot \dfrac{4}{\sin 50}=4.906726388...[/tex]

[tex]\implies b=\sin 60 \cdot \dfrac{4}{\sin 50}=4.522063499...[/tex]

Step-by-step explanation:

First, find the rate of change of the line:

[tex]\displaystyle \frac{-y_1 + y_2}{-x_1 + x_2} = m \\ \\ \frac{-6 + 3}{-1 + 2} = m \hookrightarrow \frac{-3}{1} = m \\ \\ \boxed{-3 = m}[/tex]

Now plug all the information into the Slope-Intercept Formula. It does not matter which ordered pair is chosen:

[tex]\displaystyle 3 = -3[2] + b \hookrightarrow 3 = -6 + b; 9 = b \\ \\ \boxed{\boxed{y = -3x + 9}} \\ \\ OR \\ \\ 6 = -3[1] + b \hookrightarrow 6 = -3 + b; 9 = b \\ \\ \boxed{\boxed{y = -3x + 9}}[/tex]

Step-by-step explanation:

Point-slope form of a linear equation: [tex]y-y_1=m(x-x_1)[/tex]

(where [tex]m[/tex] is the slope and [tex](x_1,y_1)[/tex] is the point)

Given:

Substituting these values into the point-slope formula:

[tex]\implies y-4=\dfrac12(x+5)[/tex]

[tex]\implies y-4=\dfrac12x+\dfrac52[/tex]

[tex]\implies y=\dfrac12x+\dfrac{13}2[/tex]

Slope-intercept form:

[tex]y=\dfrac12x+\dfrac{13}2[/tex]

Answer:

16.97m

Step-by-step explanation:

We know that, all the 4 sides of a square are equal.

Given that,

Perimeter of the square is 48m

First, let us find the length of a side the square.

For that, let the length of a side be x.

Therefore,

x + x + x + x = 48

4x = 48

Divide both sides by 4.

x = 12 m

Now let us find the length of the diagonal using Pythagorean theorem.

For that let the length of the diagonal be y.

So,

12² + 12² = y²

144 + 144 = y²

288 = y²

√288 = y

16.97 m = y

Therefore,

The length of the diagonal is 16.97m

Step-by-step explanation:

The equation that shows the number of minutes, x, it will take for the tank and the container to have the same amount of water will be 340 - 6x = 6x.

Based on the information given, the equation that shows the number of minutes, x, it will take for the tank and the container to have the same amount of water will be 340 - 6x = 6x. Therefore, the number of minutes will be:

340 - 6x = 6x

Collect like terms

340 = 6x + 6x

340 = 12x

x = 340/12

x = 28.33 minutes.
