The answer would be B. As you can see Angle A and angle B are connected by that line and together they would equal 90 degrees like on the other side of line AB.
- 3x + 2x + 5 + 5x + 15 = 180 [angles on a line add to 180 degrees]
- 10x + 20 = 180 [combine like terms]
- 10x = 160 [subtract 20 from both sides]
- x = 16 [divide both sides by 10]
Arc AB measures 3(16) = 48 degrees.
Arc BC measures 2(16) + 5 = 41 degrees.
Volume Of A Cube = s^3 = (1/3)^3 = 1/27
There Are 8 Cubes In A Prism.
ThereFore, The Volume Of The Prism Is 8(1/27) = 8/27 Cubic Centimeters.
Hope This Helps!
3(20 - b) = 36
60 - 3b = 36
-3b = 36 - 60
-3b = - 24
b = -24/-3
b = 8 <==
Answer:
Gah! Inverses!
Step-by-step explanation:
This is a pretty simple concept, just switch the x and f(x) values!
If you don't understand, look at how I solve it!

Switching the positions of the x and f(x) values...

Note: That f(x)^-1 is the proper notation for inverse functions.

There you go!
Hope this helps, and don't procrastinate!
