The first one since the given measurements/guide is Side, Angle, Side
Here is some thoughts on this:
cos 57 = sin (90-57) = sin 33
so cos 57 . cosec 33 = cos 57 / sin 33 = sin 33 / sin33 = 1
2 cos 60 = 2 * 1/2 = 1
so the last 2 parts work out to 0
now we have to find cos 70 / sin 20
sin 20 = cos 70 so this comes to 1
so finally the answer is 1
Answer:
- Point W = (-3, 3)
- Point X = (-3, 2)
- Point V = (-2, 3)
<em>The rotation rule states that rotation 90° counterclockwise means (x, y) = (-y, x)</em>
<u>The new points would be equal to:</u>
- Point W' = (-3, -3)
- Point X' = (-2, -3)
- Point V' = (-3, -2)
Try graphing it to see if the new points make sense<em>(because I'm not too sure :\)</em>
X=4
y=-4
hope this helps u out :)
