Answer:
a = B
b = E
c = D
d = A
e = C
Step-by-step explanation:
Use the Pythagorean theorem.
a² + b² = c²
7² + b² = 25²
49 + b² = 625
b² = 576
b = √576
b = 24
The answer is A.

The area of the sector is 86.81π mm²
<u>Explanation:</u>
Given:
Radius of the sector, 25mm
Angle, α = 50°
Area of the sector, A = ?
We know:
Area of the sector = 
On substituting the value, we get:

Therefore, the area of the sector is 86.81π mm²
Expanded=4x+12+6x+12
Simplified=10x+24
