Question

I need help with my homework. Angles and measurements.. I will give a medal how can help me through all. It's only about 5.

Answer 1

post the questions?

Answer 2

find the measurements..

Answer 3

the entire this is 90+55 = 145

Answer 4

thing*

Answer 5

Okay. And the second one is Sketch the standard position in 55 degrees

Answer 6

Im not sure if that's right.

Answer 7

@Euler271

Answer 8

rotate it 180 so that at the arrow points down-right. that would be 135 degrees in the standard poistion

Answer 9

125 degrees**

Answer 10

Oh okay, is it possible you can draw the pic..?

Answer 11

@Euler271 ..

Answer 12

ya

Answer 13

Find the measure of an angle between 0 degrees and 360 degrees coterminal with an angle of -110 degrees in standard position. And thanks !

Answer 14

Go around the circle once. That's 360. You can add or subtract 360 as many times as you like.

Answer 15

Okay the last one. Find the cosine and sine of 210 degrees.

Answer 16

@Numb3r1

Answer 17

That angle gives a very special triangle: if you subtract 180 degrees (which changes the sign of the sine and cosine from - to +) you have 30, which creates a 30-60-90 triangle.

Answer 18

its in the negatives.. like I thought it was -1, 0

Answer 19

The sides of that triangle come in the ratio \[1/2:\sqrt3/2:1\]

Answer 20

It isn't -1,0. That's 180 degrees, not 210.

Answer 21

the options is -1,0 ; -0.5,-0.87; -0.55, -0.95 ; -0.87, -0.5 @Numb3r1

Answer 22

-.5 is -1/2, so that must be right.

Answer 23

Ok thank youu

Answer 24

And if you look at the angle, it's closer to the y-axis than the x-axis, so that must be the y value.
