606 is the answer because a palindrome means that you can read it left to right or right to left and the number or word will not change in meaning. by the way shouldn't this be an English question.
Answer:
m= -90 is your answer
Step-by-step explanation:
For future reference, you should try using Symbolab, it works really well and I use it ALL the time!
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 ![d=\sqrt{\left(x_{2}-x_{1}\right)^{2}+\left(y_{2}-y_{1}\right)^{2}}.](https://tex.z-dn.net/?f=d%3D%5Csqrt%7B%5Cleft%28x_%7B2%7D-x_%7B1%7D%5Cright%29%5E%7B2%7D%2B%5Cleft%28y_%7B2%7D-y_%7B1%7D%5Cright%29%5E%7B2%7D%7D.)
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
![d=\sqrt{\left(2-4\right)^{2}+\left(1-5}\right)^{2}} = \sqrt{\left(2\right)^{2}+\left(4}\right)^{2}}=\sqrt{20}}.](https://tex.z-dn.net/?f=d%3D%5Csqrt%7B%5Cleft%282-4%5Cright%29%5E%7B2%7D%2B%5Cleft%281-5%7D%5Cright%29%5E%7B2%7D%7D%20%3D%20%5Csqrt%7B%5Cleft%282%5Cright%29%5E%7B2%7D%2B%5Cleft%284%7D%5Cright%29%5E%7B2%7D%7D%3D%5Csqrt%7B20%7D%7D.)
So the side AB measures
units long which is the second option.
