the angles of a triangle are consecutive multiples of 5.find the biggest angle
=====================
Let A = the largest angle
Then, since they are consecutive multiples of 5, the other two angles are A-5 and A-10
The sum of the 3 angles is 180 deg:
A + A-5 + A-10 = 180
3A - 15 = 180
A = 65
So the largest angle is 65 deg.
