Question

What is the value of x?
A) 12
B) 39
C) 45
D) 33

Answer 1

x^2 = 15^2 + 36^2

X^2 = 225 + 1296

X^2 = 1521

x = sqrt(1521)

x =39

Answer 2

This is a right triangle, so we can use the Pythagorean Theorem to find x; the Pythagorean Theorem is a^2 + b^2 = c^2, where c is the hypotenuse. In this case, x is the hypotenuse. Let's set up an equation:

15^2 + 36^2 = c^2
225 + 1296 = c^2
1521 = c^2
39 = c

Answer:
x = 39
