Answer:
The height of the triangle is always the measurement of a line (often shown as dashes) that is perpendicular to the base and extends to the opposite angle at the top of the triangle.
If it is a right triangle, and the right angle is at the bottom, the side extending up from the right angle will be the height. But this is not always the case.

Answer:
1.) 3
Step-by-step explanation:
<u>Divide each side by -35. Whatever you do to one side of the equation, you must do to the other side.</u>

X = 3
Slope-intercept form:
y=mx+b
m=slope
b=y-intercept
Data of the first line:
m=-5
b=y-intercept=3 (y-intercept=it is the value of "y" when x=0)
y=-5x+3
A line perpendicular to the line y=mx+b will have the following slope:
m`=-1/m
Therefore: the line perpendicular to the line y=-5x+3 will have the following slope:
m´=-1/(-5)=1/5
Point-slope form of a line: we need a point (x₀,y₀) and the slope (m):
y-y₀=m(x-x₀)
We know, the slope (m=1/5) and we have a point (3,2) therefore:
y-y₀=m(x-x₀)
y-2=1/5(x-3) (point-slope form)
y-2=(1/5)x-3/5
y=(1/5)x-3/5+2
y=(1/5)x+7/5 (slope-intercept form)
Answer: the line perpendicular to the first line will be: y=(1/5)x+7/5
