Question

please do this with the steps so I can understand this

If 6/square root x^2+4(square root end)=2, then x^2=?

Answer 1

6/√(x^2 + 4) = 2
square both sides
36/(x^2 + 4) = 4
4x^2 + 16 = 36
4x^2 = 20
x^2 = 5

Answer 2

in the following lines l and m are parallel, line t is a transversal. find the missing angles angle x, angle y

/ indicates a line that passes through m and l named t


m--------y/120--------

l---------60/x--------
