Mathematics Question on Exponential and Logarithmic Functions
In this figure PQ ⊥ RS and RT ∥ PQ. if ∠PST = 68° then find reflexive ∠RTS.
A
(A) 134°
B
(B) 292°
C
(C) 234°
D
(D) 102°
Answer
(B) 292°
Explanation
Solution
Explanation:
Given:PQ ⊥ RSRT ∥ PQ∠PST = 68°Calculation:RT ∥ PS⇒ ∠PST = ∠RTS = 68° (Alternative angles)Reflexive ∠RTS = 360° - ∠RTS⇒ 360° - 68° = 292°∴ Reflexive ∠RTS is 292°Hence, the correct option is (B).
