Answer:

The numbers are 44 and 36

Step-by-step explanation:

n + n - 8 = 80

2n - 8 = 80

2n (- 8 + 8) = 80 + 8

2n = 88

2n/2 = 88/2

n = 44

44 - 8 = 36

Sin  

Cos  

Tan  

So you need to use tan.

Tan = opposite / adjacent, so rearrange the formula to make opposite the subject:

[tex]Opp = Tan * adj

So simply plug these values in:

[tex]Opp =131 * tan(17) = 40.05

So the goal post is 40.05 feet tall
