Question

please solve the question​

Answer 1

a=67 b=48

Step-by-step explanation:

angle(ABM)+angle(ABC)=180 [linear pair]

angle(ABC)=180-132

=48

b=angle(ABC)=48 [alternate angles]

a+angle(ABC)+angle(ACB)=180 [angle sum property]

a=180-(48+65)=67

Answer 2

Answer:

a=67°, b=48°

Step-by-step explanation:

b+132°=180°=>b=48°(angles on same side of transverse line are supplementary)

now, angle ABC=b=48°(alternate interior angles)

So by angle sum property of a triangle,

a+65°+48°=180°=>a=180°-113°=67°
