3pi r 2 603.43 is the answer
An inscribed angle in a semicircle is always90 degrees
Work out 180-96 cus it’s on a straight line then work out 180-130 then add them then and take away from 180
The answer is D. -24 - 49i/13
Answer:
∠A = ∠B = 80°
Step-by-step explanation:
The angles are corresponding angles where a transversal crosses parallel lines, so are congruent. That means ...
∠A = ∠B
8x -8° = 5x +25° . . . . . substitute the given expressions
3x = 33° . . . . . . . . . . . . add 8°-5x
x = 11° . . . . . . . . . . . . . . divide by 3
Then the angles are ...
8·11° -8° = 80°
