D. 1, 5, 7, 9, 11, 14, 16

Step-by-step explanation:

The following angles has the same measure as <3 = 20°:

m<7 = m<3 (corresponding angles are congruent)

m<5 = m<3 (alternate interior angles are congruent)

m<1 = m<3 (vertical angles are congruent)

m<14 = m<3 (corresponding angles are congruent)

m<16 = m<3 (alternate exterior angles are congruent)

m<9 = m<14 = m<3 (corresponding angles are congruent)

m<11 = m<9 = m<3 (vertical angles theorem and corresponding angles theorem)

Therefore, angles labelled D. 1, 5, 7, 9, 11, 14, and 16 all have the measure of 20°.

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
