I think those are the answers, hope that helped.
Answer:
The perpendicular line would be y = -2x - 4
Step-by-step explanation:
First we must solve the original equation for y.
x - 2y = 7
-2y = -x + 7
y = 1/2x - 7/2
In order to find the equation of this line, we first have to note that perpendicular lines have opposite and reciprocal slopes. Therefore, since the original line has a slope of 1/2, we know the new line will have a slope of -2. Now we can use that information along with the given point in point-slope form to find the equation.
y - y1 = m(x - x1)
y - 2 = -2(x + 3)
y - 2 = -2x - 6
y = -2x - 4
The answer would be
7/11=0.6363636364
Answer:
57°
Step-by-step explanation:
Angles EGB and EHD are corresponding angles of two parallel lines cut by a transversal; therefore, they are congruent.
m<EGB = m<EHD = 57°
