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
