From the diagram above, find x
-
A.
65o -
B.
50o -
C.
75o -
D.
55o
Correct Answer: Option A
Explanation
∠RTS = 90o (∠ in semi circle)
∠UTS = 25o (∠ in alternate segment)X + 90 + 25 = 180(sum of ∠s on a str line)X + 115 = 180 X = 180 – 115X = 65o
∠RTS = 90o (∠ in semi circle)
∠UTS = 25o (∠ in alternate segment)X + 90 + 25 = 180(sum of ∠s on a str line)X + 115 = 180 X = 180 – 115X = 65o
