a^2+ b^2= c^2 -Write formula
3^2+b^2=5^2- Plug in numbers
9+b^2=25- Square each number
-9          -9- Subtract 9 both sides
b^2=16- Square root b and 16
b=4

Sin 70= 40/x - Find what side you're solving for and use Sin, Cos or Tan. Set us equation.
0.939= 40/x - Use scientific calculator to figure out what Sin 70 is.
0.939/1=40/x - Set us equation to cross multiply
x=42.59ft - Divide 40 by 0.939
