Answer 3:
Step-by-step explanation:
Solution 1:
A.T.Q:
x = (90 - x) + 30
x = 90 + 30 - x
x + x = 120
2x = 120
Solution 2:
A.T.Q:
4x + 5x = 180
9x = 180
Solution 3:
A.T.Q:
x - y = 48 — (a)
We know:
Sum of supplementary angles = 180
So, x + y = 180 — (b)
Adding (a) & (b):
x - y + x + y = 48 + 180
2x = 228
Putting value of x in (a):
114 - y = 48
114 - 48 = y
