4. Angles C and D are supplementary angles
with a sum of 1809. If the measure of Angle o
is 33 more than six times the measure of Angle
D, write and solve a system of equations to
find the number of degrees in each angle,
20
2D
Number 4
Answer:
∠C = 159°
∠D = 21°
Explanation:
∠C + ∠D = 180 (1)
∠C = 33 + 6∠D (2)
Substituting (2) to (1):
180 = 33 + 6∠D + ∠D
= 33 + 7∠D
180 - 33 = 7∠D
147 = 7∠D
21 = ∠D
If ∠D = 21,
∠C + 21 = 180
∠C = 180 - 21
∠C = 159
