HELP ASAP:
tekilochka [14]

Answer:

Here's how I would do it.  

Step-by-step explanation:

If two triangles are similar, corresponding sides are in the same ratio.

We know the measures of b and a, so we can calculate the ratio b/a.

d and b are in the same ratio, so

\begin{array}{rcl}\dfrac{d}{c}& = & \dfrac{b}{a}\\d & = & c \times \dfrac{b}{a}\\\end{array}

We know the measures of c, b, and a, so we can calculate the value of d.
