Which statements are true for the image below? Check all that apply.

A triangle has angles C, A, 33 degrees. The exterior angle to angle with measure of 33 degrees is D, the exterior angle to A is B, the exterior angle to angle C is 128 degrees.
Measure of angle B = measure of angle C + 33 degrees
Measure of angle B = 180 degrees minus (measure of angle D + 128 degrees)
Measure of angle B = 360 degrees minus (measure of angle D + 128 degrees)
Measure of angle D + measure of angle B + 128 degrees = 360 degrees
180 degrees = measure of angle D + measure of angle B + 128 degrees = 360 degrees
Measure of angle D = 360 degrees minus 33 degrees
Measure of angle D = 180 degrees minus 33 degrees
Measure of angle B = measure of angle D + 128 degrees

Answer:

a and d

Step-by-step explanation:

i think

The statements that are true for the image below are:

A. m∠B = m∠C + 33° (exterior angle theorem)

C. m∠B = 360° - (m∠D + 128°) (sum of exterior angles)

D. m∠D + m∠B + 128° = 360° (sum of exterior angles)

G. m∠D = 180° - 33° (angles on a straight line)
