Determine two coterminal angles (one positive and one negative) for each angle. Give your answer in radians. (Enter you answer as a comma-separated list)

The answer is below

Step-by-step explanation:

Coterminal angles are angles with the same terminal side at standard position (angles with the initial side on the positive x-axis).  Coterminal angles may have different magnitude but they would have equal sides and vertices.

Coterminal angles can either be positive or negative. The positive coterminal is gotten by adding 2π rad or 360° while the negative coterminal is gotten by subtracting 2π rad or 360°.

a)

Positive coterminal angle =

Negative coterminal angle =

b)

Positive coterminal angle =

Negative coterminal angle =

answer: i think one of the answer is $150 and $300?

step-by-step explanation:

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.
