Yup that is correct, that is the way to convert measurements of angle from radians to degrees. because 2pi is equivalent to one revolution of a circle and in degrees is equal to 360 degrees, then simplifying it 360 / 2pi = 180 / pi.
so <span>the measure of 0 is A radians and B degrees, then A = 180 B/pi</span>
Answer:

Step-by-step explanation:
The number inside the square root symbol is the number you have to get when you multiply a certain number twice.
So
:
What multiplied by itself is 121?
Backwards equation:


Do not do the backwards method all the times, it does not work for all numbers.
The given equations satisfy the given conditions. There are
2 equations and 2 unknowns, so a certain solution can be found.
This can be solved using substitution,
Substituting eqn 2 to eqn 1:
2(2y – 10) + 3y =1240
Simplifying,
y = 180
x = 350
Answer: D. ALL OF THE ABOVE
Step-by-step explanation:
AN INTEGER IS A WHOLE NUMBER THAT IS NOT A FRACTION
