Do question D with image​

Answer 1

Answer:

180º

Step-by-step explanation:

One of the properties we have learnt about is:

"The sum of the all angles at on side of the line is 180º". They can also be referred to as a linear pair.

And as seen in the picture, ∠ROQ, ∠QOP and ∠POU all lie in one side of the line, so the sum of their angles will be 180º.

Therefore, your answer is 180º.

Hope this helps you.
