Answer:

D. 4

Explanation:

The 55 degree angle can be either a base angle or the apex angle.

The 6 inch length can be either the length of the base or the length of each leg.

There are therefore 4 possible triangles:

1. 55 degree base angle and 6 inch leg length

2. 55 degree base angle and 6 inch base length

3. 55 degree apex angle and 6 inch leg length

4. 55 degree base angle and 6 inch base length

(2 with only 1 angle of 55 degrees (1 with the equal sides of 6 inches each, 1 with the unequal side of 6 inches)

2 with 2 angles of 55 degrees (1 with the equal sides of 6 inches each, 1 with the unequal side of 6 inches).)
