Answer:
y = 50 x = 10.
Explanation:
Let's solve for y first.
We know the line angle 80 and angle 2y-5 is on a 180 degree line.
Now we can do our work:
180 - 85 = 95
2y - 5 = 95
95 + 5 = 100
100 ÷ 2 = 50
2(50) - 5 = 95?
The equation is correct, therefore y = 50.
No we do the same thing for the other angles, 90 and 3x + 55.
Again, 180 line.
180 - 95 = 85
3x + 55 = 85
85 - 55 = 30
30 ÷ 3 = 10
3(10) + 55 = 85?
The equation is correct therefore x = 10.
Thus, y = 50 and x = 10.
