angle B? - answer a. 30°
The figure shows three lines that intersect at point N. 3 lines intersect. Lines G K and J
M intersect at point N to form a right angle. Line H L intersects the other lines at point N.
Angle H N G is 48 degrees. Angle GNH is congruent to angle KNL. Angle MNL is
complementary to angle KNL. What is the measure of angle MNL? - answer a. 42°
Points A, B, and C are on line AC. A horizontal line has points A, B, C. A line extends
from point B up and to the left to point D. Angle D B C is 140 degrees. Angle CBD has a
measure of 140°. What is the measure of angle ABD? - answer a. 40°
Angles A and B are supplementary. Angle A has a measure of 80°. What is the
measure of angle B? - answer The measure of angle B is 100°.
Angles 1 and 2 form a right angle. 2 lines form a right angle. Another line extends
between the 2 lines to form 2 angles. The top angle is labeled 1, and the bottom angle
is labeled 2. Which word describes their measures? - answer c. complementary
Given: Angle1 is complementary to Angle2. Angle2 is complementary to Angle3. Prove:
mAngle1 = mAngle3 3 separate angles are shown. The angles are labeled 1, 2, 3 from
left to right. A 2-column table with 7 rows. Column 1 is labeled statements with the
entries angle 1 is complementary to angle 2, angle 2 is complementary to angle 3,
question mark, measure of angle 1 = 90 degrees minus measure of angle 2, measure of
angle 2 + measure of angle 3 = 90 degrees, measure of angle 3 = 90 degrees minus
measure of angle 2, measure of angle 1 = measure of angle 3. Column 2 is labeled
reasons with the entries given, given, definition of complementary angles, subtraction
equality property, definition of complementary angles, subtraction equality property,
transitive property. What is the missing statement in step 3 of the proof? - answer b.
m1 + m2 = 90°
Angle ACD is supplementary to angles ACE and BCD and congruent to angle BCE. 2

the angles in the diagram? Select three options. - answer b. Angle BCE is
supplementary to angle ACE.
c. Angle BCD is supplementary to angle BCE.
e. Angle BCD is congruent to angle ACE.
