A is the answer! Your welcome!
If the length of a side is x, then the surface area of a face of the cube is x squared. there are six sides in a cube so 6(x^2) would be the surface area.
6(x^2)=150
(x^2)=25
x=5
The value of x in the triangle is (a) 22
<h3>How to solve for x?</h3>
The complete question is in the attached image.
From the attached image of the triangle, we have:
