Answer:
You can do this by dividing the radicand by the square number , and multiplying the radical by the root of that number.
e.g.
I would actually use division. So divide 56 by 8, and you'll get 7.
Or you can multiply 7 times 8 and get 56.
Hope this helps!

Recall that all three angles in a triangle equals 180.
Knowing this, we just have to add up all the angles and figure out what the value 'x' is.
(x-22 + x-17 + 3x+19) = 180
Simplify:
5x - 20 = 180
Add 20 to both sides:
5x = 200
Divide both sides by 5:
x = 40
Now that we found the value for x, we need to solve for angle A.
Simply input the value of 'x' into angle A's equation:
40 - 22 = 18
Angle A = 18 degrees
Good luck! If you need me to explain anything, just ask :))
