Answer:

37.89051724=x

Explanation:

We can use similar triangles and proportions to solve. Put the same side of the small triangle over the large triangle.

MA MB

------- = ----------

MN MP

80.5 -35 x

------------- = ----------

70.5 96.6 -x

Simplifying

45.5 x

------------- = ----------

70.5 96.6 -x

Using cross products

45.5 (96.6-x) = 70.5x

Distribute

4395.3 - 45.5 x = 70.5x

Add 45.5x to each side

4395.3 - 45.5 x+45.5x = 70.5x+45.5x

4395.3 = 116x

Divide each side by 116

4395.3/116 = 116x/116

37.89051724=x
