In the figure, PQ is a parallel to ST and QRS = 40o. Find the value of x
-
A.
55o -
B.
60o -
C.
65o -
D.
75o
Correct Answer: Option A
Explanation
From the figure, 3x + x – 40o = 180o
4x = 180o + 40o
4x = 220o
x = (frac{220}{4})
= 55o
From the figure, 3x + x – 40o = 180o
4x = 180o + 40o
4x = 220o
x = (frac{220}{4})
= 55o
