The 2nd and 4th expressions are the appropriate ones. Both result in '0' which means that Kiana is on the ground floor of the building at the end.
Answer:
B is the correct answer
Step-by-step explanation:
Angles 1, 2, and 3 added together should make 180 degrees.
So, if angle 2 is 70 degrees, you subtract 70 from 180 (180-70=110) and you're left with 110 degrees.
Angle 1 and 3 add together should make 110 degrees which makes B the only true statement.
The answer would be 1 1/7
The coefficient of determination is the first one. I'm pretty sure.
