Question

The angle measures of a triangle are (x-9), x, and (2x-5). Find the measures of the angles.

Answer 1

By angle sum prop. of a triangle:

∠A+∠B+∠C = 180°

∴ (x-9)+x+(2x-5) = 180

x-9+x+2x-5 = 180

4x-14 = 180

x = 180+14\4

x = 48.5

Therefore all the angles are:

∠A = x-9 = 39.5°

∠B = x = 48.5°

∠C = 2x-5 = 92°

Answer 2

Sum of angles of triangle=180
x-9+x+2x-5=180
4x-14=180
4x=180+14=194
x=194/4=48.5
1st angle=x-9=48.5-9=39.5
2nd angle=x=48.5
3rd angle=2x-5=2*48.5-5=97-5=92
