Answer:
1. a + b + c = 180
2. b + d = 180
3. d = a + c
Step-by-step explanation:
1. a + b + c = 180:
Angles in a triangle add up to 180
2. b + d = 180:
Angles in a straight line equal 180 because they are supplementary angles
3. d = a + c:
ΔACD is an exterior angle, and ΔACB is interior adjacent, hence ∠a and ∠c add up to ∠d
Answer:
The answer is D

Coplanar means that they are on the same closed area(or plane)- P, M, C, N are all on the same Plane.
Answer:
W = - 14
Step-by-step explanation:
13W - 2(4W + 1) = W - 58
13W - 8W - 2 = W - 58
13W - 8W - W = 2 - 58
4W = - 56
W = - 56 : 4
W = - 14
