Some newly schools question and answer inquired students to indicate what they ponder is the main important element for a student to do if they wanted to hit success. One that response stood out from the rest was practice. Successful persons are certainly not born successful; they become successful through hard work and dedication. If you want to complete your goals, keep this in mind! beneath are one of the answer and question example that you could certainly utilise to practice and elevate your knowledge and also give you insights that might just help you to keep up your study in school.

## Question:

In the diagram, what is the measure of WRS?

O 5°

O 7.5°

O 25°

O 37.5°

## Answer:

**Answer : The measure of ∠WRS is 25°.**

**Step-by-step explanation :**

As we know that vertically opposite angles are always equal.

**In the given figure,**

∠VRT = ∠WRS = (5x)° (Vertically opposite angles)

And we know that the sum of all angle in a straight line is equal to 180°.

So,

∠TSR + ∠WRS = 180°

Given: ∠TSR = (25x + 30)°

(25x + 30)° + (5x)° = 180°

30x + 30° = 180°

30x = 180° – 30°

30x = 150°

**x = 5°**

∠WRS = (5x)° = (5 × 5)° = 25°

**Therefore, the measure of ∠WRS is 25°.**

They could possibly hopefully assist the student resolve the question by working with the questions and answer examples. You would possibly then have a discussion with your classmate and continue the school learning by studying the topic as a group.
