Answer:

Arc CR = 90 deg

=> angle CBR = 90 deg

=> angle CBV = 90 deg

=> 3x + 4 = 90

=> 3x = 86

=> x =~28.7 deg

=> Option A is correct

Hope this helps!

Answer:

A: x = 28.7

Explanation:

Since VR is the diameter and CB is bisecting it so arcVC= arcCR and

<CBV = <CBR

NOW

3x+4 = 90

3x = 90-4

3x = 86

Dividing both sides by 3

x ≈ 28.7
