Question

plz answer with steps ​

Answer 1

ANGLE 1 = 70  (ALTERNATE ANGLE OF ANGLE PQR)

                        (ALTERNATE ANGLES ARE EQUAL)

ANGLE 1 + ANGLE 2 + 45 = 180(SUM OF ANGLES OF STRAIGHT LINE

70 +ANGLE 2+45=180

115 +ANGLE 2=180

ANGLE 2=180-115

ANGLE 2=65

NOW ANGLE 2 +ANGLE 3 + 70=180(SUM OF ANGLES OF TRIANGLE IS 180)

65+ANGLE 3+70=180

135+ANGLE 3=180

ANGLE 3=180-135

ANGLE 3=45
