Answer: I think 91.9
Step-by-step explanation:
If I remember right, all the angles of a triangle add up to 180 degrees. So taking 22.8 + 65.3 = 88.1, then 180 - 88.1 = 91.9
Sorry if that’s not right! I just wanted to take a crack at it.
Answer:
Step-by-step explanation:
We can write the equation of a line in 3 different forms including slope intercept, point-slope, and standard depending on the information we have. We have a point (8,1) and a slope from the equation y=-23x+5. We will chose point-slope since we have a point and slope.
Point slope:
in our new equation because it us perpendicular to it. This means we will need to change it into its negative reciprocal which is .
We will substitute and .
.
This is the equation of the line perpendicular to y=-23x+5 that crosses through (8,1).
Pete's equation is 50+75h (this means 50+7 times 3 because h represents hours and it tells us that there are 3 hours so h is 3)
paul's equation is 75+50h(this means 75+50 times 3 because h represents hours and it tells us that there are 3 hours so h is 3)
paul charges less because 75+50h equals to 225 and 20+75h equals to 275 and 275 is more than 225 so paul charges less(paul is cheaper)
