Answer:
43y
Step-by-step explanation:
31y+12y
combine like terms
Factor out y
y( 31+12)
y (43)
43y
Vertical angles are equal to each other:
∠2 = ∠3
5 + 4y = 6y - 25
→ 30 = 2y
→ 15 = y
∠2 = 5 + 4y = 5 + 4(15) = 5 + 60 = 65
linear pairs equal 180:
∠1 + ∠2 = 180
→ ∠1 + 65 = 180
→ ∠1 = 115
Answer:
45 miles
Step-by-step explanation:
first divide miles/minutes: 15 / 20 = 0.75
then multiply: 0.75 x 60 = 45
X = 180 - 58 - y
Y = 180- 126= 54
X= 180 - 58 - 54
X= 180- 112= 68 degrees
