The measure of an angle is 4y. find the measure of its complement.

Sum of supplement = 180

so 180 - 4y is another supplement angle

answer is B) (180 - 4y)°

its 42 hope this helps!

B)(180 - 4y)°

Step-by-step explanation:

180 should be the answer

The answer is C. (180 - 4y) I took the USATP

The two angel must add to 180 since they are supplements, so

x+4y=180

x+4y-4y=180-4y

x+0y=180-4y

x+0=180-4y

x=180-4y

x=-4y+ 180

so the final answer is -4y+180

you welcome

B)(180 - 4y)°

B)(180 - 4y)°

Explanation:

B)(180 - 4y)°

B)(180 - 4y)°

Step-by-step explanation:

Supplementary angles are two angles that forms a total of 180 degrees. If the measure of an angle is 4y degrees, then the measure of the supplementary angle is 180-4y. That is letter B.

Complementary angles are angles whose measure add up to 90°.

So, if one angle is 4y, the complementary angle is 90°- 4y. Choice A.

Complementary angles does not necessarily need to share a line or vertex. As long as both angles have a sum of 90°, then, they are complementary angles.

Angles who has a sum of 180° are called supplementary angles.
