Answer:
5
Step-by-step explanation:
Hello :
the line passes by O(0,0) : an equation is : y = mx
so : y=2x.....(<span>the equation of a line with slope m=2 and point (0,0))</span>
X+2x+5x=180
8x=180
4x=90
x=90/4
x=22,5
the angles are 22,5, 45, 112,5
x+2x+3x=180
6x=180
x=180:6
x=30
the angles are 30,60, 90
Are you sure the ex is correct???
