SOLUTION: one angle of a trangle is three times another. the third anngle is 25 degrees more then the smallest angle. find the angle of the smallest angle.

Question 192948: one angle of a trangle is three times another. the third anngle is 25 degrees more then the smallest angle. find the angle of the smallest angle.

Let x=smallest angle
3x=second angle
x+25=third angle
.
We know that the sum of the angles of a triangle is always 180, so:
x+3x+(x+25)=180
5x+25=180
5x=180-25
5x=155
x=31
second angle=3x=3*31=93
third angle=x+25=31+25=56
So the smallest angle is 31 degrees.
