The actual length of a in the triangle shown is 10 cm. Use the scale drawing of the triangle to find the actual length of side b.

B is 1.5 cm.

Thats not an answer can you explain how you got it?

To find the actual length of side b, we first need to find the scale factor between the scale drawing and the actual length. Since side a in the scale drawing is 9 cm and the actual length of side a is 10 cm, the scale factor is 10 cm / 9 cm = 10/9.

Next, we can find the actual length of side b using the scale factor. In the scale drawing, side b is 1 cm. To find the actual length of side b, we multiply the length in the scale drawing by the scale factor: 1 cm * (10/9) = 10/9 cm = 1.11 cm.

Therefore, the actual length of side b is 1.11 cm.
