Answer:
35 i guess, for the sum of 120 degree angle
Answer:
<u>Step-by-step explanation:</u>
This is a special triangle because the side lengths have the following relationship:
30° ⇄ side length "a" <em>represented as "h" in your picture</em>
60° ⇄ side length "a√3" <em>represented as "g" in your picture</em>
90° ⇄ side length "2a" <em>represented as "√5" in your picture</em>
<u>Step 1: solve for "a" </u> <em>hypotenuse (2a) is given as √5</em>
According to your picture, a = h, so
<u>Step 2: use the a-value from Step 1 to solve for the remaining side</u>
