Question

please please long answer step by step solution 9th class​

Answer 1

Answer:

x + y = 127

Step-by-step explanation:

external angle = sum of two opposite internal angles

here 127° is the external angle of triangle PQR

so x, y are opposite internal angles of triangle PQR

so x + y = 127°

hope this answer is helpful to you

Answer 2

Step-by-step explanation:

MY DEAR BROTHER/SISTER

ANGLE PRQ+PRO=180

ANGLE PRQ=180-127(LINEAR PAIR)

ANGLE PRQ=53°

NOW ANGLE PRQ=ANGLE BPR(ALTERNATIVE INTERIOR ANGLE)

SO ANGLE BPR=53°

ANGLE BPR+ANGLE RPQ +ANGLE APQ=180°(LINEAR PAIR)

53°+ANGLE RPQ+50°=180°

ANGLE RPQ(y)=77°

SO IN TRIANGLE PQR

ANGLE SUM PROPERTY

ANGLE RPQ+PRQ+PQR(x)=180°

77+53+ANGLE PQR=180°

ANGLE PQR=50°

x is ANGLE PQR AND y is ANGLE RPQ

SO x+y=50°+77°=127°

ANS:-127°
