In this unit, you've learned about trigonometry and its applications to right triangles and real-world scenarios that can be modeled

with right triangles. In such scenarios, sometimes we refer to an angle of elevation or depression. Both types of angles have one side

that is horizontal. From this side, the angle may open up (angle of elevation) or open down (angle of depression). These images show

the difference between the two.

angle of depression

angle of elevation

In this task, you'll apply what you've learned to answer questions about a skateboard ramp that you and your friends are building for

your community skate park. The ramp will lead up to a platform. You'll be using a piece of wood that's 3.5 meters long for the ramp,

and the ramp's angle of elevation will be 28°. Use this figure as a model to answer the questions that follow.

platform

ramp

UNO [17]

Answer:

<em>2 solutions</em>

Step-by-step explanation:

Given the expression

2m/2m+3 - 2m/2m-3 = 1

Find the LCM of the expression at the left hand side:

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

open the bracket

4m²-6m-4m²-6m/(4m²-9) = 1

Cross multiply

4m²-6m-4m²-6m = 4m² - 9

-12m = 4m² - 9

4m² - 9+12m = 0

4m² +12m-9 = 0

<em>Since the resulting equation is a quadratic equation, it will have 2 solutions since the degree of the equation is 2</em>

Triangle ABC is shown on the graph. What are the coordinates of the image of point B after the triangle is rotated 270° about th

irina [24]

The coordinates of the image of point B after the triangle is rotated 270° about the origin is (4, 2)

<h3>How to determine the image of point B?</h3>

The complete question is added as an attachment

From the attached image, we have the following coordinate

B = (-2, 4)

When the triangle is rotated by 270 degrees, the rule of rotation is:

(x, y) ⇒ (y, -x)

For point B, we have:

B' = (4, 2)

Hence, the coordinates of the image of point B after the triangle is rotated 270° about the origin is (4, 2)
