Answer:
y = 12 degrees
x = 40 degrees
Step-by-step explanation:
Triangle BDE: 3y + 54 + 90 = 180
3y + 144 = 180
3y = 36
y = 12
Line AC: angles on a straight line = 180
116 + 54 = 170
so, angle EBC = 10
Triangle BCE: 10 + 90 + 2x = 180
100 + 2x = 180
2x = 80
x = 40
To find the x-intercepts algebraically, we let y = 0 y=0 y=0 in the equation and then solve for values of x. In the same manner, to find for y-intercepts algebraically, we let x = 0 x=0 x=0 in the equation and then solve for y.
