Question

6. Calculate x in the following figure

Answer 1

Answer:

X = 18

Step-by-step explanation:

15^2 = 12^2 + a1^2

15^2 = 12^2 + a2^2

a1 = 225 - 144 = 81

a2 = 225 -144 = 81

root 81 is 9

a1 = a2 = 9

a1 + a2 = 18

mark me as brainliest

Answer 2

answer :

(x/2 )² = ( 15² - 12²) by Pythagoras theorm

x²/ 4 = ( 225 - 144)

x² / 4 = 81

x² = 81 × 4

x = √ 81 x 4

x = 9 × 2

x = 18
