All of the angles are 60 degrees because it is a equallaterial triangle.
4x+5=10x+3
6x=2
x=1/3
4x+5
4(1/3)+5
4/3+5
=6 1/3
we know that,
the roof the colosseum=
(x-h)^2+(y-k)^2=r^2
where
(h,k) is the center and r is the radius
now,
(h.k)=(0,0)---(orgin)
we know that radius is half the diameter
so,
r=600/2=300
now substitute the value,
(X-0)^2+(y-0)^2=300^2
x^2+y^2=90,000
hope it helps you
6). y=3
7). x=-2
I hope this helped.
