Question

Find the value of x to the tenths place

Answer 1

x = 15

[x = 15.0]

Explanation:

we can find the length of the hypotenuse of a right triangle using the Pythagorean theorem

[note: "c" is what they are referring to as "x" here]

a² + b² = c²

a : 12

b : 9

[c = hypotenuse/x/unknown side]

12² + 9² = c²

144 + 81 = c²

225 = c²

√225 = √c²

15 = c

{x = 15.0}
