Answer:
10.29
Step-by-step explanation:
use Pythagorean theorem
side opposite to 90 is always hypotenuse
and we know
h^2=p^2+b^2
you can put any side as perpendicular or base.
Answer:
Option C: b is parallel which is; y = ½x - 1
Step-by-step explanation:
We know that if the slope of a line is m, then the slope of the line that is perpendicular to it would have be; -1/m.
In this question, m = ½
Thus, the slope of the line that is perpendicular to it is; -1/(½) = -2
However, to find the slope of the line parallel to it would mean that the value of m which is the original slope will remain the same. Original slope = ½, thus the only option with slope as ½ is option C where b is parallel with the equation; y = ½x - 1
