Question

Identify PR rounded to the nearest tenth. Please help asap!!

Answer 1

Trigonometric Functions:

`S(O)/(H) C(A)/(H) T(O)/(A)`

`Sine(Opposite)/(Hypotenuse) Cos(Adjacent)/(Hypotenuse) Tan(Opposite)/(Adjacent)`

You have the angle and the adjacent. You need to find the hypotenuse (PR). Therefore, you use cos.

`Cos(26)=(13)/(H)`

Rearrange the formula to find H (PR):

`H = (13)/(Cos(26))`

14.463 ~ 14.5

14.5°
