Answer:
8.95
Step-by-step explanation:
here we are going to use pythagoras theorem
a² +b² =c²
the vertical can be taken as a and horizontal as b
4² +8²=c²
this is the same as
c²= 4²+ 8²
c²= 16+ 64
c²=80
to get rid of the square we shall put both sides under a root
c = 8.95
Y - y1 = m(x - x1)
slope(m) = 1...because a parallel line will have the same slope
(1,-5)...x1 = 1 and y1 = -5
now we sub
y - (-5) = 1(x - 1) =
y + 5 = 1(x - 1) <== u could leave that first " one " out if u want...
The expression is: 5x + 6y - 3
√4 / 9
√4 = 2
So the answer would be....
2 / 9
Hope this helps!
If the height is h, then h/65=sin70, so h=65sin70=61.08m approx.
