Answer:

Option B. 49.5 degrees

Step-by-step explanation:

Given that arc QS measures 4x-18

Arc QS is a semicircle and hence subtended angle by semicircle at the centre is 180 degrees.

Use this to find the value of x

4x-18 = 180 degrees

Add 18 to both sides

4x=198

Divide by 4

x =198/4 =49.5

So answer is option B

49.5 degrees
