It would be zero
See how the Y are the same so if you were to graph it you would get a flat line and it wouldn't be undefined cause that when the X has the same value.
A right triangle has one 90 angle.
The sum of the three angles of any triangle is equal to 180 degrees.
180-90= 90 degrees.
The answer is C.
How can expressions be written and evaluated to solve for unknowns in the real world?
Writing expressions requires figuring out which quantity in a situation is unknown, and define a variable to represent that quantitiy.
We look for words in the problem that will help us out what kind of operation to use in a given situation.
Example:
Donna bought 5 chocolate bars, and then ate some. Write an expression to represent how many chocolate bars Donna has left.
If we let the variable c represent the number of chocolates Donna has eaten, then we can write the expression on how many bars Donna has left as: 5 - c
