Answer:
angle four equals angle 7 because they are alternate angles in a way.
Step-by-step explanation:
First if you go diagonally up from angle 4, you get angle 5. Then you go diagonally down. That angle isn't marked so I'll call it Z. But you could do it a faster way. You see, you could replace angle 4 with angle Z and vice versa. Then angle Z is the alternate angle of angle 7. One rule you should remember:
Alternate angles are equal.

Answer:
A=2, B=3, C=5
Step-by-step explanation:
Two polynomials are equal for all values of the variable if the corresponding coefficients are the same. The way to solve the problem is to multiply the RHS, rewrite it in a more orderly way

Now, for the two polynomials to be the same we need to have, at the same time

You might notice that we have more conditions than variables, but you can consider one of the two in the middle as a "check" option.
Now, grabbing the value from the first condition into the second we get B=3. Replacing both value in the third we see that the equality still holds, and replacing into the fourth we get C =5.
