Question

What’s the value of x???

Answer 1

x = 2

Explanation:

x is the height of these triangles. Thus, we know all three sides of either triangle: height = x; base = 8/2, or 4; and hypotenuse √20.

Using the Pythagorean Theorem, we find x as follows:

x^2 + 4^2 = 20, or

x^2 = 4. Then x must be 2.

x = 2
