Answer:
x=2√5
Step-by-step explanation:
<u>1st method:</u>
sin(30)=opposite/hypotenuse=√5/x
sin(30)x=√5
x=√5/sin(30)
x=2√5
<u>2nd method:</u>
cos(60)=adjacent/hypotenuse=√5/x
cos(60)x=√5
x=√5/cos(60)
x=2√5
<u>3rd method:</u>
This is a 30-60-90 triangle, so we can multiply the short side, √5, by 2, to get x=2√5
For a more see orthocenter of a triangle .The orthocenter is the point where all three altitude of the triangle intersect. An altitude is a line which passes through a vertex of the triangle and is a perpendicular to the opposite side. Hope this helps :)
Answer:
2x
Step-by-step explanation:
6x^2
-------
3x
6/3 =2
x^2/x =x*x/x =x
6x^2

Answer:
48 ft
Step-by-step explanation:
this is because the perimeter of the room is its sides so first you 9x2=18
then 14x 2= 28 and then 28 + 18 and you get 48 ft
