2 - 8 years
3 - 9ft
Let's say that the hypotenuse is length 1.
In a 45 45 90 triangle, the legs are equal to the hypotenuse * (1 / [sq rt (2)])
So if the hypotenuse =1, the legs equal 1 /

Answer:
x = 8
Step-by-step explanation:
Asuming the equation is 8x-4=60°,
Simplifying
8x + -4 = 60
Reorder the terms:
-4 + 8x = 60
Solving
-4 + 8x = 60
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '4' to each side of the equation.
-4 + 4 + 8x = 60 + 4
Combine like terms: -4 + 4 = 0
0 + 8x = 60 + 4
8x = 60 + 4
Combine like terms: 60 + 4 = 64
8x = 64
Divide each side by '8'.
x = 8
Simplifying
x = 8
