I'm guessing d b are equal and a and c are equal or I don't think we would be able to solve so going on that
if angle d is 57 angle b must also be 57
A parallelegram has angles that add up to 360
So 360= 57+57+2c
Solve
360=114+2c
-114 both sides
246=2c
÷2 both sides
123=c

Hi!
(l = Lenny
m = Max)
Lenny is 3 times as old as Max.
3m = l
When you subtract Max's age from Lenny's age, you get 24.
L - m = 24
Put in the value of l.
3m - m = 24
There is our equation.
Now solve
2m = 24
2m/2 = 24/2
m = 12
3 * 12 = l
36 = l
The equation is 3m - m = 24
Max is 12 and Lenny is 36.
Hope this helps! :)

V= π r^2 h
r= radius
h= height
If the radius was 10 ft and the height was 12ft then the answer be about 3769.91.
However if it was reversed and the radius was 12ft and the height was 10 ft then the answer would be about 4523.89.
3769.92≈ π 10^2 12
or
4523.89≈ π 12^2 10

Answer:
43.20
Step-by-step explanation:
First we need to find the sales tax
tax = price * tax rate
tax = 40 * 8%
= 40*.08
=3.2
We final cost is the price plus the sales tax
final cost = price + tax
= 40+3.2
= 43.20
