Question

are these angles acute, obtuse, right, or reflex?
θ=200°
θ=r/6

Answer 1

What is r? radius?

Answer 2

Did you mean pi/6?

Answer 3

i think r is the radius, it has a cursive r/6 in the problem

Answer 4

wait my fault, i think it is pi. sorry for the confusion. that was dumb of me

Answer 5

If an angle is obtuse then it is greater than 90°
If an angle is acute, then it is less than 90°
If an angle is right, then it equals 90°
If an angle is reflex, then it is between 180° and 360°

Answer 6

yes i understand that part

Answer 7

oh so if it is 200 degrees then it is reflex?

Answer 8

Yes

Answer 9

so pi/6 would be acute right?

Answer 10

oh i see

Answer 11

i have another one that says 5pi/3, that would be acute as well right?

Answer 12

pi = 180 so

5(180)/3 = 5(60)

Answer 13

oh so it would be 300, but why does pi=180?

Answer 14

so it would be reflex
