Answer:
Step-by-step explanation:
∠6 = 45 {Vertically opposite angles are equal}
∠6 + 5x + 35 = 180 {Co interior angles}
45 + 5x + 35 = 180 {add like terms}
80 + 5x = 180
5x = 180 - 80
5x = 100
x = 100/5
x = 20
5x + 35 = 5*20 + 35 = 100 + 35 = 135
∠8 = 5x + 35 { Corresponding angles}
3) ∠8 = 135
4) ∠ 3 = ∠6 {Alternate interior angles are equal}
∠3 = 45
5) ∠6 = 45
Steps:
$549/4 people
= $137.25/person
20% of $137.25
= 0.2 x 137.25
= $27.45
$27.45 + $137.25
= $164.70
therefore, mike will pay $164.70: $27.45 as a tip to the deckhand and $137.25 for his individual share of the entire trip.

Y + 1 = -1/4(x - 5)
y + 1 = -1/4x + 5/4
y = -1/4x + 1/4
B. y = -1/4x + 1/4
Step-by-step explanation:
x²+x-12=0
by factorization
x²-3x+4x-12=0
taking common
x(x-3)+4(x-3)
(x+4)(x-3)
x= -4. x=3
