Question

calculate the value of x​

please give me the answer

Answer 1

Answer:

Step-by-step explanation:

using pythagoras theorem on both triangles, we can find the bases

so lets say the line measuring 12 divides it in half then

(x/2)= $\sqrt{15^{2} - 12^{2}$ = $\sqrt{225-144$ = $\sqrt{81}$ = 9

=> x = 9x2 = 18
