tan x = opp/hyp
x is the side of the building and 6 is the distance from the bottom of the ladder to the building
tan 13 = 6/x
multiply both sides by x
x tan 13 =6
divide both sides by tan 13
x = 6/ tan 13
x = 26
The ladder goes 26 ft up the building
Answer:
3y^2 - (y + 2) (y - 2) = 0
<=> 3y^2 - (y^2 - 4) = 0
<=> 2y^2 + 4 =0
<=>y^2 + 2 = 0
=> Because y^2 is always equal or larger than 0, there is no real solution.
Hope this helps!
