Answer:
43
Step-by-step explanation:
The triangle is split into two similar triangles. They have the same shape but not the same size. To solve, write a proportion.
[tex]\frac{67.2-32}{67.2}=\frac{x}{81.9-x}[/tex]
[tex]\frac{35.2}{67.2}=\frac{x}{81.9}[/tex]
Cross multiply to solve for x.
35.2(81.9 = 67.2(x)
2,882.2= 67.2x
43=x
