Answer: right triangle since it has a right angle of 90°
Explanation:
Answer:
The missing value is 2
Step-by-step explanation:
A direct variation satisfies the equation
.
Since the point (-18, 12) lies on this line, it must satisfy this equation.


Hence the equation of this line is 
Now we substitute x=-3 to find y.

Therefore the missing value is 2
To solve a problem like this, we can setup a basic algebraic equation.
52+14=x
66=x
We know this equation is true because 14 years ago, she was 52 so 14 years later, she is 66.
