Answer:
#1= 24.23
#2= 57.91
#3= 35.84
#4= 48.59
Step-by-step explanation:
soh cah toa
sin=opposite/hypotenuse
cos=adjacent/hypotenuse
tan= opposite/adjacent
use inverse sin cos and tan to find angles!
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°
