Question

Solve for x
9 in
x in
12 in

Answer 1

x = 15in

Explanation:

We can use the Pythagorean theorem to solve since this is a right triangle

a^2 + b^2 = c^2 where a and b are the legs and c is the hypotenuse

9^2 + 12^2 = x^2

81 +144= x^2

225 = x^2

Take the square root of each side

sqrt(225) = sqrt(x^2)

15 =x
