The second angle of a triangle is 4 times as large as the first. The third angle is more than the sum of the other two angles. Find the measure of all three angles.
It would help if you proofread your questions before you posted them.
Let x = first angle, the 4x = second, but how much more is the third angle? (x+4x+?)
They will add to 180º.
