Question

Last one and I’m done :’) help

Answer 1

Example 1 tan-1(9/20)=24.23°

Example 2 cos-1(17/32)=57.91°

Example 3tan-1(13/18)=35.84°

Example 3 sin-1(21/28)=48.59°

Answer 2

#1= 24.23

#2= 57.91

#3= 35.84

#4= 48.59

Explanation:

soh cah toa

sin=opposite/hypotenuse

cos=adjacent/hypotenuse

tan= opposite/adjacent

use inverse sin cos and tan to find angles!
