don't spam as it is really urgent and important...​

Answer 1

Step-by-step explanation:

AD/DB=AE/EC. (by thales theorem)

(x+10)/(4x+10) = (x+6)/(x+10)

(x+10)*(x+10) = (4x+10)*(x+6)

(x+10)² = 4x²+(10+6)x+10*6

x²+10²+2*10*x = 4x²+16x+60

x²+100+20x = 4x²+16x+60

x²+20x-4x²-16x = 100-60

20x-3x²-16x = (40)

4x-3x² = (40)

x-3x²= 40/4

x-3x²=(10)
