Twice the sum of the first two angles of a triangle is 54 greater than the third angle. If the second angle is 6 greater than the first, what is the measure of the largest angle?

Sagot :

the answer is 60 , 54 plus 6 equals 60 , so 60 is the answer.
The 3 angles are 54, 60 and 66. The largest angle is 66
