Answer:
8
Step-by-step explanation:
The fact that DE is perpendicular to AC means triangles AED and CED are congruent and side AD is equal in length to side CD.
5x -20 = 2x +4
3x = 24 . . . . . . . add 20-2x
x = 8 . . . . . . . . . .divide by 3
The value of x is 8.
Solution
A=4πr2=4·π·82≈804.24772
Approximately = 804.25
The area of a triangle is A = (b*h)/2:
(5 * 8)/2 = 20
