Tn=3n-5
therefore: T(3)=3(3)-5
T(3) =4

Step-by-step explanation:
base is 12, hypotenuse is 20
so X² is h²-b²
so X=16
The correct answer is 17 what i did was plug in 17 where ever you see x so x2 would be 17x2 an then plus the 5 gives u 39 3x 17x3=51 51+10=61 now add the totals 61 plus 39 gives u 100
