Step-by-step explanation: yes yes no yes no I think. I think it’s no for cylinder and cube bc if u cut them, it’ll be the same shape but also the same size
Are you sure this is the COMPLETE problem?
Expand
13x - 16 - 10x = 12 - 11x
Simplify 13x - 16 - 10x to 3x - 16
3x - 16 = 12 - 11x
Add 16 to both sides
3x = 12 - 11x + 16
Simplify 12 - 11x + 16 to -11x + 28
3x = -11x + 28
Add 11x to both sides
3x + 11x = 28
Simplify 3x + 11x to 14x
14x = 28
Divide both sides by 14
x = 28/14
Simplify 28/14 to 2
x = 2

Step-by-step explanation:
Using the slope formula:

Have you considered applying the Law of Cosines?
For angle B: b^2 = a^2 + c^2 - 2ac*cos B
a, b and c are all known, leaving cos B as the only unknown. Find cos B, and then find angle B itself. From the diagram we know that angles A, B and C are all acute.
