Question

The measures of 2 angles in a triangle are equal. The third angle measures twice the sum of the equal angles Find the measures of the three angles

Answer 1

Answer:

The three angles are 30° , 30° , 120°.

Step-by-step explanation:

$a+a+2(a+a)=180\\6a=180\\a=30\\so \\a =b =30\\c=2(a +b )=2*(30+30)=120$
