Answer:
20π square units
Step-by-step explanation:
The area of a sector is given by ...
A = (1/2)r²θ
where r is the radius and θ is the central angle in radians.
Filling in your numbers, we find the area to be ...
A = (1/2)(10²)(2/5π) = 20π
The area of the sector is 20π square units.

Answer:
C. 57
Step-by-step explanation:
all triangles add up to 180. the tick marks show that ∠D and ∠ E are congruent so you do this and solve for x:
(4x + 1) + (4x + 1) + (5x - 4) = 180
13x - 2 = 180
13x = 182
x = 182/13
x = 14
4(14) + 1 = 57
Answer:
72
Step-by-step explanation:
It showed us the formula to solve it.
12x12 = 144
144 divided by 2 = 72
72 is the answer.
