Answer:
16.23
Step-by-step explanation:
Use cosine to solve.
cos = adjacent / hypotenuse
cos 52 = 10 / x
(x = AB)
(cos 52)(x) = 10
x = 10 / (cos52)
x = 10 / 0.616
x = 16.2338
AB = 16.23
SO first you want to change it to Y=mX+b by getting the y by itself. Subtract 3x over and have -6y=-3x=12 divide both sides by -6 and have y=1/2x-2. To get the perpendicular slope you flip it 1/2 to 2 then change its sign 2 to -2
The new slope is -2

Step-by-step explanation:
3 times 4.23=12.96
Midpoint equals the average of the two coordinates.
F=(G+H)/2
2F=G+H
H=2F-G, given that F=105 and G=32
H=2(105)-32
H=210-32
H=178
