In the diagram, MQ//RS, o and o. Find the value of x
Attached Figure / Diagram
A
150o
B
110o
C
100o
D
95o
Verified Correct Answer: C.
Step-by-Step Mathematical Solution
L + 30o - 180o(Sum of o - 30o = 150o
L = q = 150o(opposite o(alt. o(sum of o + c 180
c = 180 - 30
c = 150o
b = a = 30o (opp o (opp o = 180o (sum of o + k + 70o = 180
k + 100o = 180
k = 180 - 100
k = 80o
x + 80o = 180(sum of o - 80o
x = 100o
