*The ratio of the measures of the three triangles in a triangle is 10:3:7 Find the measure of the longest angle*

Do you mean the **largest** angle?

Add up 10 + 3 + 7 to get 20. Then the largest angle is (10/20) x (180^{o}) = **90 ^{o}**

The other two angles are (3/20) x (180^{o}) = 27^{o}

and (7/20) x (180^{o}) = 63^{o}
