Answer:
x=9
Step-by-step explanation:
Ur answer is c to ur question
You know from trigonometry that AB = 15 units, so the area of the larger triangle ACB is (1/2)*15*15 = 112.5 units^2.
Then the area of triangle ADE is
.. (112.5 -62.5) = 50 . . . . units^2
20 % = 225
1% = 225 / 20
100% = 225 * 100 / 20
= 1125 answer
