Question

1) Find the sine of Angle 1.

2) Find the cosine of Angle 1
3) find the sine of angle 2
4) find the cosine of Angle 2
5) use inverse sine or inverse cosine to find the measure of angle 1

Answer 1

Explanation:

sin(angle 1) = 5.2/6 = 26/30 = 13/15

cos(angle 1) = 3/6 = 1/2

sin(angle 2) = cos(angle 1) = 1/2

cos(angle 2) = sin(angle 1) = 13/15

angle 1 = 60 degrees [cos60 = 1/2 - identity]
