So a line that is perpendicular is a line that intercepts other line at a 90 degree angle.
Slope of perpendicular lines is the opposite sign and the reciprocal of the other.
So if your slope was 2 the perpendicular line would have a slope of -1/2.
So the equation, 2x + y = 3
Can be rewritten as
y= -2x+3
Perpendicular slope: 1/2
Since it intercepts/ passes the coordinates (5,4) it means that those values are included in the function input x and output y.
y=mx+b
4=1/2(5)+b
Solve for b (y intercept)
4-2.5=b
1.5=b
So the equation of the perpendicular is
y=1/2x+3/2 or y=.5x+1.5
E.
I think this will be the answer :)
Answer:
NO because 7+5=12
The sum must be larger (not equal to) the longest side. If it's exactly the same, there's no room to for the shorter two sides to angle up to form a triangle.
Answer:
82%
Step-by-step explanation:
4237-742 = 3495
3495/4237=0.824876
0.824876*100= 82%
Answer:
AC = 20
Step-by-step explanation:
Δ BDE and Δ BAC are similar, so the ratios of corresponding sides are equal, that is
= 
, substitute values
= 
( cross- multiply )
4AC = 80 ( divide both sides by 4 )
AC = 20
