Question

One angle of a triangle is 45* greater than the smallest angle, and the third angle is 5* less than twice the smallest angle. Find the measures of the three angles.
smallest angle --- x
the other is ------ x+45
third ------ 2x - 5

solve for x:
x + x+45 + 2x-5 = 180
x+x+45+2x-5=180
4x+40=180
4x=180-40
4x=140
x =140/4
x=35..


Smallest angle =35
The other is =35+45=80
Third =2X35-5=70-5=65
