Question

What’s the value of x???

Answer 1

Answer:

x = 2

Step-by-step 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
