Answer:
Explanation:
A) ∠QRS = 90 degrees (The angle of the triangle opposite to the diameter is always 90)
Given that QR = 68 degrees
So,
∠RSQ =
∠RSQ = 68/2
∠RSQ = 34 degrees
Now, Finding ∠RQS
∠RQS = 180-90-34
∠RQS = 56 degrees
B) ∠SRT = ∠QRS - ∠QRT
=> ∠QRS = 90 (Mentioned above) , ∠QRT = 56 (Given)
So,
∠SRT = 90-56
∠SRT = 34 degrees
