Question

Goodmorning , please help!

Answer 1

3.5

Explanation:

If AM=5, then so is MC because the angles are equal.

So AC must be 5+5 = 10.

If BD=17, you can subtract AC=10, so you keep 7 for BA + CD.

Since these angles are also equal, you can divide 7 evenly so you get:

BA = CD = 7/2 = 3.5

Answer 2

7/2

Explanation:

17=x+x+10

17-10=2x

7=2x

x=7/2
