What are the remaining angle measures if the figure is to be a parallelogram?
mZB=
mZC=
m2D =

The answer is given below

Step-by-step explanation:

Given that the parallelogram ABCD has m∠A = 79°

A parallelogram is a quadrilateral with two pairs of parallel lines. For a parallelogram, opposite sides of a parallelogram is equal and opposite angles are also equal. Also the diagonal of a quadrilateral bisect each other.

m∠C = m∠A = 79° (opposite angles of a parallelogram are congruent)

m∠C = 79°

m∠B +  m∠A = 180° (consecutive angles of a parallelogram are supplementary)

m∠B + 79 = 180

m∠B = 180 - 79

m∠B = 101°

m∠B = m∠D = 101° (opposite angles of a parallelogram are congruent)

m∠D = 101°

to find the perimeter of the rectangle this is the expression:

x-9+x-9+3x-4+3x-4=138

if we simplify it:

8x-26=138

remember, 138 is what it all adds up to

the length is 11.5cm

the width is 57.5cm

the area is 661.25cm^2
