Answer:
A) ∠AOB = 36°
Step-by-step explanation:
The full circle area = 10²π or 100π
the shaded portion is (10π/100π)(360°) = 36°
Answer:
cos(55) = 11/x
Step-by-step explanation:
We have the hypotenuse (x) and an angle adjacent to 55 (11). The only trigonometric formula that uses adjacent and hypotenuse is cosine (adjacent/hypotenuse), so that will be your answer.
