Answer:
Angle A: 72°
Angle B: 108°
Step-by-step explanation:
Opposite angles are equal
Adjacent angles add up to 180
5y - 3 = 3y + 27
2y = 30
y = 15
Angle A:
5(15) - 3 = 72°
Angle B:
180 - 72 = 108°
Answer:
a makes sense to me
Step-by-step explanation:
Answer:
D. 5y^2 - 4y - 1
Step-by-step explanation:
Combine like terms:
(y^2 -y +1) +(4y^2 -3y -2)
= y^2(1 +4) +y(-1-3) +(1 -2)
= 5y^2 -4y -1
Answer:
You would use tangent/toa
Step-by-step explanation:
Because at each point you have to find, you have the info for the opposite and the adjacent
