Question

Sin(theta)=-sqrt(2)/2, what is the angle measure?

Answer 1

Answer:5pi/4, 7pi/4, and 13pi/4

Explanation:

Just did this on edge

Answer 2

sin ( theta ) = - √2 / 2
We will use the unit circle:
m ∠( theta ) = 225° = 5π / 4 + 2 k π , k ∈ Z
m ∠( theta ) = 315° = 7π / 4 + 2 k π, k ∈ Z
Answer:
The angle measure is 5π/4 or 7π/4.
