Question

pls answer this asap its an emergency

Answer 1

proved below

Step-by-step explanation:

since AD || BC

with transversal AC,

<C = 48° (Alternate Interior Angles)

then

A+B+C = 180° (angle sum property of triangle)

84 + B + 48 = 180

180-132 = B

<B = 48

since <B = <C (48°)

then AB = AC (isoceles triangle property)

hope it helps
