Question

What is the value of x to the nearest tenth?

Answer 1

Let's find the height of the triangle. Whatever the height is, when we double it, it'll be x. We need to use the pythagorean theorem.

12²+(x/2)²=18²

144+(x/2)²=324

(x/2)²=180

x/2=13.4164079

x=26.833

X≈26.8

So, the answer is the first option, 26.8.
