Which is the radian measure of an angle whose sine is 0.8? Round your answer to two decimal places.
0.93
–2.22
2.33
4.06

Which is the degree measure of an angle whose tangent is 1.19? Round the answer to the nearest whole number.
48°
–48°
50°
–50°

Answer 1

sin of the angle = 0.8
so sin inverse of 0.8 would give you the angle = 53.1
now change this into radians by multiplying by pi/180 = 0.93

Answer 2

tan inverse of 1.19 would give you the angle which would be 49.9 = 50 degrees
