Answer:
The triangle should be 16 inches wide.
Step-by-step explanation:

What we know:
- One of the legs measures 12 inches.
- The hypotenuse is 20 inches.
We need to solve for b. Solving for a while b is 12 would also be acceptable.

We will use the first equation.


The triangle should be 16 inches wide.
Answer:
The missing angle is 128°
Because corresponding angles are equal.
The angle pair is called <em><u>corresponding</u></em><em><u> </u></em><em><u>angles</u></em><em><u> </u></em>
There are many solutions. But what do you mean with a perfect square of a number. I thought a number IS a perfect square or not.
For example, the difference between 2² and 4² = 12, which is twice the number 6, which is √36
The difference between 2² and 6² = 32, which is twice the number 16, which is a perfect square.
So choose depending on your interpretation of the question... ;-)
The graph is still a straight line, it still cuts the y-axis at the point y=4 ,
and it still slants up from left to right.
But it becomes a lot less steep. The original line only had to go <em>4 inches</em>
to the right in order to rise 1 foot. The new line has to go <em>3-feet</em> to the right
in order to rise 1 foot.
