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.

In the triangle below.
Sergeu [11.5K]

Answer:

(1)  36.6 feet

Step-by-step explanation:

m∡Q = 180-(90+55) = 35

sin 35°/21 = sin 90°/PQ

cross-multiply to get:

21 = sin35·PQ

21/sin 35 = PQ

PQ = 36.6
