You have a right triangle here so we are going to use a trig identity to solve for y. Y is the side opposite the angle given to us, and then we also have the hypotenuse. Opposite / hypotenuse tells us that we have to use the sin ratio to find y. .
In order to isolate the y, we will multiply both sides by 37 to get
37sin(52)=y. We can do this on our calculator in degree mode and will get that y = 29.156 inches
Answer:
a
Step-by-step explanation:
Using the tangent ratio in the right triangle
tan15° = =
( multiply both sides by x )
x × tan15° = 20 ( divide both sides by tan15° )
x = ≈ 74.6 ft ( to the nearest tenth of a foot )
