A. 12
B. 10
C. 225
D. 16


​

Answer 1

Answer:

A

Step-by-step explanation:

paythagorian pramey

AC^2= AB^2+BC^2

BC^2 = AC^2-AB^2

x^2 = (15)^2-(9)^2

x^2 = 225-81

x^2= 144

x =√144

x=12

Answer 2

Answer:

a] 12

Step-by-step explanation:

By pythagoras theroem,

AC^2 = AB^2 + BC^2

(15)^2 = (9)^2 + BC^2

225 = 81 + BC^2

225 - 81 = BC^2

BC^2 = √144

BC = 12 - [by taking square root on both sides]

Hence, the value of 'x' is 12 units.
