The sum of AB and BC is 180 degrees. So 13x - 10 = 180. 13x = 190.
x = 190/13
What are your options for the questions.
The equation of a line that passes through (x1,y1) and has a slope of m is
y-y1=m(x-x1)
find slope
slope between (x1,y1) and (x2,y2) is
(y2-y1)/(x2-x1)
given
(-3,2) and (2,1)
slope=(1-2)/(2-(-3))=(-1)/(2+5)=-1/5
pikc a point
if we pick (-3,2)
(x1,y1)
x1=-3
y1=2
y-2=-1/5(x-(-3))
y-2=-1/5(x+3)
that is D
Round up to 1, 400 then times it by 5
1,400 • 5 = 7,000
So no, it it's not reasonable.
Area of a square =a^2
40000=a^2
a=200 inch
Now if u can imagine a square shape with side of 200 inch each.it makes right angles
so use pythagorean theorm
c^2=a^2+b^2
c^2=(200)^2+(200)^2
c=282.84 inch
ength of a fence is 282.84 inch
