Question

Find the unknown angle in the following figure​

Answer 1

Answer:

x=70

Step-by-step explanation:

55 and p are same because of the small line in between them

then add them both 55+55=110

then subtract 110 from 180 because a triangle equals to 180

tada you got your answer

Answer 2

Answer:

80degree

Step-by-step explanation:

PQ=PR

angle QPR=angleQRP(angle opposite to equal sides are equal)

angle QPR+angleQRP+anglePQR=180degree

(angle sum property)

50degree+50degree+anglePQR=180degree

anglePQR=180degree-100degree

80degree
