## anonymous one year ago In a 30°-60°-90° triangle, the length of the hypotenuse is 30. Find the length of the longer leg.

@LegendarySadist i cant figure it out

2. Nnesha

hypotenuse is the longest side of the right triangle

3. anonymous

The longer "leg" Nnesha. 2 legs and a hypotenuse.

Ok, in a 30-60-90 triangle, all of the sides can be calculated when you have the length of one of them. |dw:1433437621277:dw|

B) $10 \sqrt{3}$

8. anonymous

The length of the side opposite to the 30 degrees (also known as the short leg) is always half of the hypotenuse.

C) $15 \sqrt{2}$

You don't have to make a separate tab for each choice...

D) $15 \sqrt{3}$
