Answer:
Step-by-step explanation:
hello :
use pytagor-rule :
triangle ABC : (x+15)² =17²+y²....(*)
triangle BDC : y² = x²+8²....(**)
by (**) put the value of y² in (*) :
(x+15)² = 17²+x²+8²
x²+30x+15² = 17²+x²+18²
30x +225 = 289+64
30x = 128
x= 128/30
x= 64/15
put this value in (**) calculate y² ......continu
