In 22, you're looking for the vertical height of the triangle. You're given the angle opposite the side you want to find (which I'll call x) and the length of the hypotenuse. This sets you up with the relation

\sin2^\circ=\dfrac x{1600}\implies x\approx55.84\text{ m}

In 23, you're given a similar situation, except now you're looking for the angle (I'll call it \theta) in the triangle opposite the side denoting the height of the airplane. So this time,

\sin\theta=\dfrac{1500}{5000}=\dfrac3{10}\implies\theta=\arcsin\dfrac3{10}\approx17.46^\circ

Find the slope and y-intercept of the line that is
Vlad [161]

Remark

Perpendicular slopes are found by using the formula m1*m2 = - 1. That is followed by using the given point to determine the y intercept.

Solution

<em><u>Step One</u></em>

Find the slope of the new line

m1 = - 1/3

m2 = ??

m1 * m2 = - 1

(-1/3) * m2 = - 1

You could continue by changing (-1/3) to a decimal.

(-0.3333333333) * m2 = -1    Now divide by the decimal

m2 = - 1/ (-0.3333333333)

m2 = 3 which is what my calculator tells me the answer is.

<u>Step Two</u>

So far what you have is

y = 3x + b

Use the point (-3, -7) to get the y intercept.

-7 = 3(-3) + b

b - 9 = - 7

b = -7 + 9

b = 2

y = 3x + 2 Answer

Graph

The graph shown below is both lines plotted in desmos. The red line is y = 3x + 2 which is perpendicular to the given graph y = (-1/3)x +5 which is in blue.

The green dot is the point (-3 , - 7)
