Mashutka [201]
Hey there Unrazed90,

Answer : 

100% = $25.30
1% = $25.30 / 100
      = $0.253
8% = $0.253 x 8 
      = $2.024
Total = $25.30 + $2.024
         = $27.324
         = $27

Hope this helps :D

Answer:

Step-by-step explanation:

height^{2}  = slant height^{2} - half of base diagonal^{2}  

= 92.8^{2} -19.8^{2}

= 8219.8

Then square root it, we have: \sqrt{8219.8} = 90.66

So the height is: 90.66
