Question

13.
The value of p +a+r is equal to
pº
9​

Answer 1

Answer:

D) 4 Right Angles

Step-by-step explanation:

Angle p will be

180-45=135°

Angle q will be

180-45=135°

Angle r will be

180-90=90°

135+135+90 is 360°

360 is also equal to 4 right angles

(1 right angle = 90

4*90=360)

Answer 2

Answer:

B

p=180°-x

q=180°-x

r=180°-x

p+q+r=180°-x +180°-x+180°-x =0

540°-3x=0

-3x=0-540°

-3x= -540°

x=-540°÷-3

x=180°

Which is equal to two right angles.
