Answer 1

`x=10`

Explanation:

The given triangle is a 30°-60°-90° triangle. Use the following rule:

`hypotenuse=shorter.leg*2`

We know the length of the hypotenuse, which is 20. Insert the value:

`20=s*2`

Solve for s. Divide both sides by 2:

`(20)/(2) =(s*2)/(2) \\\\10=s`

The length of the shorter leg is 10. Therefore, the value of x is 10.
