acute

reflex

supplementary

Answer 1

@pooja195 @oldrin.bataku

Answer 2

i know that a is wrong

Answer 3

it is 225 degrees

Answer 4

I'm thinking reflex but in not completely sure

Answer 5

it must be greater than 90 degrees but less than 180 degrees for obtuse.
acute angle is less than 90 degrees so that's not it either :/

Answer 6

it is reflex because our angle must be greater than 180 degrees but less than 360 degrees

for supplementary two angles add up to 180 degrees.

Answer 7

can you help me on one more? the answer i get doesn't make sense but I'm not sure if I'm missing something

Answer 8

I could try... depends on the question x.x

Answer 9

Which angle measure less than or equal to 360° is equivalent to an angle of 17π/4?

45°

135°

π°

230°

Answer 10

i got 765 degrees

Answer 11

wow that's a big angle to convert from radians to degrees.

Answer 12

I see.. so when we converted from radians to degrees we got 765 degrees

recall that 360 degrees makes 1 full circle

Answer 13

720 degrees makes 2 full circles

so you have to subtract 765-720

Answer 14

thats the part that threw me off

Answer 15

so its 45?

Answer 16

it's like when you have the degrees that's higher than 360... we have to figure out how many circles we are going to go through) like for example if I have 480 degrees... I have gone through one full circle, but I don't exceed 720 degrees.
so 480 - 360 = 120 degrees is my difference
like almost 1 and a half circle but not quite

yeah it should be 45 degrees when 765 is subtracted by 720
765-720 = 45

Answer 17

ohhhhh okay thank you so much i kinda understand better
