Welcome back WELZIE — missed you this week.
Here's a step-by-step solution for the geometry problem:
Given Information:
- RS is a diameter of the circle with center O.
- The line segment RW is tangent to the circle at point V.
- R1^=∠SRV=50∘.
1.2.1 Calculate the size of WRS^
Step 1: Identify the angle in a semicircle.
Since RS is a diameter, the angle subtended by the diameter at any point on the circumference is 90∘. Therefore, ∠RVS=90∘.
Step 2: Calculate $\angle RSV
