NEED HELP ASAP!! WILL MARK DUE TOMORROW
I don't understand, and I would really gratefully appreciate if someone would give me the answer and also explain it to me too so I can understand it forever. :) Thanks!

Sara is driving home from college for the weekend. The average speed of her car for the trip is 45 miles per hour. Write a verbal model and algebraic expression to represent the distance Sara's car travels in h hours. Identify the units for the expression.​

180-142=38 for the acute angle next to the entry

90+38=128

180-128=52

a=52

step-by-step explanation:

b

step-by-step explanation:

the equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (0, 4) and (x₂, y₂ ) = (3, - 5) ← 2 points on the line

m = = = - 3

with m = - 3 and (a, b) = (3, - 5), then

y - (- 5) = - 3(x - 3), that is

y + 5 = - 3(x - 3) → b

i would you but i don't under stand the qustion
