Given: <span>2x-y-3=0.
find </span>equation for the line perpendicular to the given line that goes through the given point:<span>
(2;-1)koord of direction vector (i`m not know how it is called at you, because i'm from russia)</span><span>
=> (x-0)/2=(y-4)/-1 (</span>canonical <span>equation)
=>x+2y-8=0(general </span><span>equation)
</span>
<span>further:
{x+2y-8=0
{2x-y-3 =0 => y=13/5 x=14/5
(14/5; 13/5) - koord point on line
</span>|dist|=sqrt( (14/5-0)^2 + (13/5-4)^2 ) = sqtr(7.72) = 2.78
Удачи!

Answer:
61 degrees
Step-by-step explanation:
A triangle has a total of 180 degrees. We already know 80 and 39. 80+39 is 119. 180-119+61
Look for the one with Parallel diagonals
No.
4 meters is 400 centimeters, so is smaller than 450 centimeters.
Your work appears to be correct.
The results from a graphing calculator are in agreement.
