Question

Find the value of y to the nearest tenth.

6.4

6.0

7.5

8.0

Answer 1

Let's consider what the question asks for:

--> the length of 'y'

To solve:

--> we need to use trigonometry

--> let's determine which function to use based on the image given

below

--> (look at image attached)

Let's use angle with measure of 53:

--> the side with length of 'y' is adjacent to it

`cos(53)=(y)/(10) \\\\y=10*cos(53)=6.02`

Thus the length of that particular side is about:

--> 6.0

Answer: 6.0
