Slope of 2y = x + 5:-
This is y = 0.5 x + 2.5 in slope intercept form so its slope = 0.5
Slope of the line perpendicular to it = -1 / 0.5 = -2
it passes through (2 , 1) so we have
y- 1 = -2(x - 2)
y = -2x + 4 + 1
The answer is y = -2x + 5

Basically, solve for n, then find aanother tha is solve for m
8n=-3m+1
divide both sides by 8
n=-3/8m+1/8
and find m
8n=-3m+1
minus 1 both sides
8n-1=-3m
divide both sides by -3
-8/3n+1/3=m
m=-8/3n+1/3
Answer: 25
Assuming the dotted line touches the middle of the base of the triangle,
Using Pythagoras Theorem,
(30/2)^2 + (20)^2 = x^2
x^2 = (15)^2 + 400
x^2 = 625
x = √625 or -(√625)
x = 25 or -25
But since x needs to be a positive value,
x = 25
