If you take 180-90 because of the right angle would be 90° then -15 you will get 75 which will be X

Answer:

x = 5

Step-by-step explanation:

From the Euclidean theorem

10^2 = x(x + 15)

100 = x(x+15) from this equation we can conclude that x = 5 and when

added to 15 it'd be 20 and multiplied by itself the result is equal to 100
