Okay - so where did i mess up? so i figured, that the top triangle's missing angle was 30 degrees. so i did 91/cos30 = 105ish for there it was just a tan(60) to get x

Check out the attached image below. I added a variable y to help find x

tan(angle) = opposite/adjacent

Focusing on the smaller 30-60-90 triangle, we see that

tan(60) = 91/y

y*tan(60) = 91

y = 91/tan(60)

y = 52.53887

now focus on the largest triangle and we see that

tan(30) = 91/(x+y)

0.57735 = 91/(x+52.53887)

0.57735*(x+52.53887) = 91

0.57735*x + 0.57735*52.53887 = 91

0.57735*x + 30.3333165945 = 91

0.57735*x + 30.3333165945 - 30.3333165945 = 91 - 30.3333165945

0.57735*x = 60.6666834055

x = 60.6666834055/0.57735

x = 105.07782697757

x = 105.1

So the final answer is approximately 105.1

x = 105.1

Explanation:

Consider two triangles:

small Δ:

    tan 60° =

⇒ y tan 60° = 91

⇒ y =

large Δ:

    tan 30° =

⇒ (x+y) tan 30° = 91

⇒ x + y =

⇒ y = - x

Solve the System:

small Δ: y =

large Δ: y = - x

⇒ = - x

⇒ - = -x

⇒ 52.5 - 157.6 = -x

⇒ -105.1 = -x

⇒ 105.1 = x

Your error was using cos (adjacent/hypotenuse) instead of tan (opposite/adjacent).

median is the value separating the higher half of a data sample, a population or probablity distribution from the lower half.

step-by-step explanation:

say you have 3,8,7,3,1,9,8 order them from lowest to highest

if orderd it would be 1,3,3,7,8,8,9 now you take away from the lowest and the highest until you end up in the middle.

so you would remove the 1 and 9 leaving you with 5 digits remaining

when you've reached the middle that would be your answer so in this case the answer is 7

if there were two numbers left say 7 and 5 you'd and them together so 12 then divide by 2 witch would equal 6 so the answer would be 6

good luck on that project hoped i you at all
