Answer:
Angle A is 37 degrees, Angle B is 82 degrees, Angle C is 61 degrees
Step-by-step explanation:
Exterior angles are the supplement of interior angles, so subtract 143 from 180 to find Angle A.
180 - 143 = 37
All angles add up to 180.
37 + 61 = 98
180 - 98 = 82
Angle B is 82 degrees.

$47.70
$45 with 6% sales tax
6%=.06
To find total amount multiply by 1.06 or multiply by .06 and that is tax amount and then add it to the $45
$45*.06=2.70 amount of tax
$45*1.06=47.70 total amount paid
Any questions feel free to ask. Have a great day!
Answer:
Step-by-step explanation:
use the point-slope formula [y-y1 =m(x-x1) ] with the given info
for the point P=(x1,y1) =(2,-2) and the slople m = -1/2
plug those into the formula
y-(-2)= -1/2(x-2)
y+2= -1/2x + 1
y= -1/2x+1 - 2
y = -1/2x - 1
:) got it?
these are hard untill you get the idea of the two formulas
point-slope: y-y1 = m(x-x1) and
slope-intercept: y= mx+b
memorizing those will help a lot
M - 12 = -3
You would be able to find what m is by finding a number that can subtract 12 and get -3.
Hope this helps and have a nice day!!!
