The value of the angular measure of v, can be found to be B. 52 degrees.
How to find the angular measure ?
The shape shows a right angled triangle within a circle. The interior angles of a triangle will always add up to 180 degrees.
As this is a right angled triangle, it means that one of the angles is already 90 degrees. This means that the value of the angle v would be:
= Total sum of interior angles - Angle measure of non - missing side
= 180 - 90 - 38
= 52 degrees
In conclusion, angle v is 52 degrees.
