Answer:
D
Step-by-step explanation:
the x (first number in the ordered pair) cant match with another x
in every other line, the x repeats which makes the function thing make a diagonal line instead. **khan academy explains it well btw**
86m^2
Triangle A and Triangle B
x = 30
if A||B, then 4x + 2x must equals to 180 (interior angles of 2 parallel lines)
6x = 180
Reasoning:
200=1/2h(10+15)
400=h(25)
16=h
I hope this helped and good luck!
