Question

In the figure < PQR = 40 º , < PRS = 100 º

and < RST = 70 º.

a) What is the measure of < QRT ?

b) What is the measure of < QPR ?

c) What is the measure of < RTS ?​​

Answer 1

Answer:

QRS=180°

SO, PRQ =180°-100° = 80°

we know that, the addition of three angles of any rectangle is 180°,

so from there, we can find , <PQR+<QRP+<QPR=180°

<QPR=180°-(40°+80°)

<QPR=180°-120°=60°
