Answer:
x = 4
Step-by-step explanation:
From the picture attached,
By using mean ratio theorem in the given triangle,
AC × CD = (BC)²
(x + 5)x = (x + 2)² [Since, AC = AD + CD]
x² + 5x = x² + 4x + 4
5x = 4x + 4
5x - 4x = 4
Therefore, x = 4 will be the answer.
(5 , 0)
7 * (−9y+4x−20)=0
9 * (−7y+16x−80)=0
-63y + 28x -140 = 0 ......a
-63y + 144x -720 = 0 .....b
b-a: 116x - 580 = 0
116x = 580
x = 5
y = (4x-20)/-9 = 0/-9 = 0
