et mA = 40°. If B is a complement of A, and C is a supplement of B, find these measures. mB = ° mC = °
1 answer:
Alright, lets get started.
We have given angle A = 40°
We are also given angle B is complement of A.
Complementary angles are two angles whose sum is 90, it means
angle B =
angle B =
angle B = 50° Answer
Now given, angle C is supplement of angle B.
Supplementary angles are two angles whose sum is 180°.
Means angle C =
angle C =
angle C = 130° : Answer
Means angle B = 50° and angle C = 130°

Step-by-step explanation:
{y = ¼x - 3}
{2x + 4y = 12
2x + 4[¼x - 3] = 12
2x + x - 12 = 12
3x - 12 = 12
+ 12 + 12
