Answer:
123°
Step-by-step explanation:
Supplementary angles add up to be 180 degrees.
This means angles A and B will add up to be 180 degrees.
We can find the measure of angle B by subtracting 57 from 180
180 - 57
= 123
So, the measure of angle B is 123 degrees
Answer:

Step-by-step explanation:
The equation of a parabola: y = ax²
The larger the value of |a|, the narrower the parabola.
We have the following coefficients a:

We arrange the coefficients from the smallest to the largest:

Therefore you have the answer:

Your answer to this is 200
For this case we must find the product of two mixed numbers:

So, we have:

If we go to a mixed number we have:

Answer:

58-180=122 x=122 hope this helps have a nice nite!
