The side AB measures option 2.
units long.
Step-by-step explanation:
Step 1:
The coordinates of the given triangle ABC are A (4, 5), B (2, 1), and C (4, 1).
The sides of the triangle are AB, BC, and CA. We need to determine the length of AB.
To calculate the distance between two points, we use the formula 
where (
) are the coordinates of the first point and (
) are the coordinates of the second point.
Step 2:
For A (4, 5) and B (2, 1), (
) = (4, 5) and (
) = (2, 1). Substituting these values in the distance formula, we get

So the side AB measures
units long which is the second option.
Answer:
7 7/8 inches
Step-by-step explanation:
Example:
Start with a 3 inch plant
3 - 1 5/8 = 1 3/8
It grows 9 1/4 but you started at threelsdjf;lasjdflkjsdfl
9 1/4 - 1 3/8 = 7 7/8
I think that the answer would be two triangles.
Answer:
15,36,39
Step-by-step explanation:
A right triangle will satisfy Pythagoras Theorem:
c² = a² + b²; where c is the longest side.
