Question 251280: In a triangle, the measures of the angles are (x-25)degrees, (3x-15) degrees
and (2/5 x)degrees What is the measure of the smallest angle?
a) 20 degrees b) 25 degrees c) 35 degrees, d) 40 degrees e) 50 degrees Answer by edjones(8007) (Show Source):
You can put this solution on YOUR website! x-25+3x-15+ 2x/5=180
4x-40 + 2x/5 =180
4x + 2x/5 = 220
20x+2x=1100 multiply each side by 5.
22x=1100
x=50
2*50/5=20 deg (smallest angle)
