You can use the Pythagorean theorem to answer this. The diagonal is the hypotenuse of the right triangle that is formed. So, your equation will look like (h is height):

We have to solve for h:


You can plug it into a calculator, and you get approximately 19.105. The answer closest to that is
B. So, that's your answer! Hope it helps. If anything doesn't make sense, hmu!
The answer to question one would be "D" y<-3
For question two the answer would be "C" x<5
Hope that helps!
Answer:
this question is not complete. need another equation
Step-by-step explanation:
give another equation then I can solve

X-13=42
x is the "variable", you're taking 13 away from that, and the answer is also given, 42.
