Question

Find the value of x.
URGENT, please help!?

Answer 1

`x=√(30)`

Explanation:

Use the geometric mean to solve for x. The side x is common to both the triangle that has the base of 3 and the triangle that has a base of 3 + 7, so x is the geometric mean. Set up that proportion as follows:

`(3)/(x)=(x)/(10)` and

`x^2=30` so

`x=√(30)`
