Question

The second angle of the trianle is 4 times larger as the first. the third angle is 80 degree more than the sum of the other two angles. find the measure of all three angles

Answer 1

first is x
second is 4x
third is 5x+80
and you know they add to 180 so write
\[x+4x+5x+80=180\]
\[10x+80=180\]
\[10x=100\]
\[x=10\]
