Find the value of x.<br> URGENT, please help!?
kotykmax [81]

Answer:

x=\sqrt{30}

Step-by-step 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:

\frac{3}{x}=\frac{x}{10} and

x^2=30 so

x=\sqrt{30}
