Question

How do you find a positive and a negative coterminal angle of 180 degrees and 20 minutes

Answer 1

Two angles a are coterminal if their sum is a multiple of 360°. What that means is that two angles are coterminal when they start and end in the same place. Examples of Coterminal angles are
180° and − 180°
170° and − 190°
100° and − 260°

Answer 2

so basically add/subtract 360 to the number you are trying to find the coterminal of

Answer 3

so what would be a postive coterminal angle of 180

Answer 4

I know its 540 but the question I have also has minutes. 360* 30'

Answer 5

before we go there what is the negative coter of 180

Answer 6

-180

Answer 7

good!

Answer 8

the min hand completes a circle on the clock when it covers 360 degree in 60 mins

Answer 9

so 1 min = 6 degrees

Answer 10

if one minute = 6 degrees than how many degrees are there in 20 min?

Answer 11

120 minutes

Answer 12

120 degrees right not minutes haha:P so now add and subtract 360 to find your coterminal angels
