ANSWER

EXPLANATION
Coterminal angles are angles in standard position that have the same terminal side.
To find an angle in standard position that is coterminal with

We add or subtract multiples of

The first addition gives,

We add the second multiple to get,

Since this is the maximum value among the options, we end the addition here.
Let us now subtract the first multiple to get,

We end the subtraction here because this is the least value among the options.
Therefore the angles that are coterminal with

are
Answer:
B
Step-by-step explanation:
Divide both 28x and -4 by 4 because a square has 4 equal sides. That comes out to 7x-1, therefore answer B is correct.
Step-by-step explanation:
We need to find thr range if

The absoulte value of something is positive.
So

This function isn't possible so no range exist.
Angle A + Angle B = 180 degrees
180 = (6x -48) + (4x +38)
180 = 10x -10
190 = 10x
x = 19
Angle A = 6x - 48
Angle A = 6 * 19 - 48
Angle A = 115 -48
Angle A = 67 degrees
Angle B = 4x + 38
Angle B = 4*19 + 38
Angle B = 76 + 38
Angle B = 114
