Question 7 (5 points)

Solve -4 + 6 sin x = -4 + 4 sin x for 0° less than or equal to x less than or equal to 180°.

135 degrees
30 degrees
180 or 0 degrees
90 degrees

Answer 1

The answer to your question is: 0° or 180°

Explanation:

Equation

- 4 + 6 sin x = - 4 + 4 sin x

0° ≤ x ≤ 180°

6 sin x - 4 sin x = -4 + 4

2 sin x = 0

sin x = 0/2

sin x = 0

x = 0° or 180°
