Question 1011828: find the measure of the largest angle in a triangle the sides are not marked other than what i'm writing on the bottom you have (x+20)deg and (2x)degrees and the top is (7x+10)degrees and can you tell me how to write the answer the acellus site is very picky on how to write the answer

Since all the angles sum to 180,
x%2B20%2B2x%2B7x%2B10=180
10x%2B30=180
10x=150
x=15
So now find each angle,
x%2B20=15%2B20=35
2x=2%2815%29=30
7x%2B10=7%2815%29%2B10=105%2B10=115
The largest angle would be 115.
