A = 60
C = 75
Hope this helps
Answer:
∠B = 135°
∠A = 60°
∠C = 75°
Step-by-step explanation:
Since, Straight Line PQ always has angle 180°
∴ ∠PBS = 180 - ∠ABC
= 180° - 45° = 135° = ∠B
Since, ∠RAS and ∠BAC are vertically opposite to each other.
So, ∠RAS = ∠BAC
Also ∠RAS = 60°
∴ ∠BAC = 60° = ∠A
The straight line ∠PCQ always has angle 180°.
∴ ∠PCR = 180 - ∠RCQ
⇒ ∠PCR = 180 - 105° = 75° = ∠C
