I think it is the Associative Property of Addition.
Answer:
Area of a triangle = A =
Step-by-step explanation:
Given Data:
height of a triangle = h = 15 in
base of a triangle = b = 2 feet = 2*12 =24 in
To Find Out:
Area of a triangle = A = ?
Formula:
Area of a triangle = A = 
Solution:
Area of a triangle = A = 
Area of a triangle = A = 
Area of a triangle = A = 
Area of a triangle = A =
Greater 1 km = 1000 m
so it's greater than 999 m
Answer:
<h2>g(3) = -2</h2>
Step-by-step explanation:

Answer:
y=70 degrees
Step-by-step explanation:
If 2 angles are complimentary, they add up to 90 degrees.
x+y=90 degrees
x=20 degrees
y=90-20 degrees
y=70 degrees
If that is wrong, try this. Let's say the questions gives us the fact that x is 20 degrees greater than y.
y=x
Substituting x for y, the equation is x+x+20=90
Since y is x, x would also be y, which is 35. then x+20 would be 55.
So y would be 35.
THE ANSWER WOULD BE <u><em>70 DEGREES</em></u>, BUT IF THAT IS WRONG, DO THE SECOND ONE, WHICH IS 35
