Answer:

The length of AB is 7.45 units.

Step-by-step explanation:

You can find the length of AB using Cosine Rule, cosθ = adj./hypo. :

θ = 20°

adj. = 7 units

hypo. = AB

cos 20° = 7/AB

AB = 7/cos 20°

= 7.45 units (3s.f)

Rotation 90 degrees counterclockwise about the origin

nataly862011 [7]

Answer:

Point W = (-3, 3)
Point X = (-3, 2)
Point V = (-2, 3)

The rotation rule states that rotation 90° counterclockwise means (x, y) = (-y, x)

The new points would be equal to:

Point W' = (-3, -3)
Point X' = (-2, -3)
Point V' = (-3, -2)

Try graphing it to see if the new points make sense(because I'm not too sure :\)
