Question

If the sin(3x + 10)º = cos(x + 24)º, find x.

A) x = 10
B) x = 14
C) x = 20
D) x = 28

Answer 1

x = 14

Since sine and cosine are equal, the angles must be complementary.

3x + 10 + x + 24 = 90

4x + 34 = 90

4x = 56

x = 14

Answer 2

B) x=14

Explanation:

Since sine and cosine are equal, the angles must be complementary.

3x + 10 + x + 24 = 90

4x + 34 = 90

4x = 56

x = 14
