Figure 3

Figure 1

Step-by-step explanation:

Figure 1 is the pre-image

The side length is 2.  We multiply the side length by the scale factor.

2 * 4 = 8

The new figure will have a side length of 8.  That will be Figure 3

Figure 2 is the pre-image

The side length is 4.  We multiply the side length by the scale factor.

4 * 1/2 = 2

The new figure will have a side length of 2.  That will be Figure 1

the answer is b.

step-by-step explanation:

by the trigonometric ratio tangent, tangent equals opposite divided by adjacent.

therefore, tan(50) equals ac/3

multiply each side by 3 to get: ac=3tan(50)

the answer is b.

3 is greater then both of those numbers
