if i have 3 ordered pairs (3,15) (12,13) (5,7) on a graph and are making a scalene triangle. The question is how to do make this into in the an equation of two of the perpendicular Bisectors. and then getting that information i am not sure how to solve it. i am thinking if i get it started i will be able to finish it but i have NO idea even how to start to get an equation set up.
THANK YOU SO MUCH!

Question 80533: A wooden board is placed so that it leans against a loading dock to provide a ramp.
The board is supported by a metal beam perpendicular to the ramp and placed on a 1 ft. tall support.
The bottom of the support is 7 feet from the point where the ramp meets the ground. The slope of the ramp is 2/5.
Find the length of the beam to the nearest hundredth of a foot. Note that the 1 ft. support is vertical, but the metal beam is not.
Could you also show how you got this answer?THx

Question 80648: I have a pizza. The radius is 10 inches long. The pizza was cut into 16 equal slices. When 1 slice was left, my sister and I both wanted it, so we agreed to cut it in half, but I like the crust more than she does, so we decided to cut it the "other way." In other words, the two pieces would not be symmetrical. The inside piece would contain all topping, and the outer piece would contain some topping and some crust.
Finally, the question: How far up the radius from the center of the circle will I need to cut so we will both have an equal area of pizza? Note: the area of the crust and topping make no difference. Just think of it as a regular circle. ?Could u please show me how you got the answers for both of these? Thanks
And Jenny and Greg have both agreed to mow half of a lawn. This lawn is a rectangle, 25 feet by 45 feet. Their lawn mower cuts a 2 feet wide path. If Jenn starts at a corner and makes a path around the outside, how many times should she go around to cut one half of the lawn?

Question 85283: A swing starts at the angle of 53 degrees to the horizontal swing. Every time the swing stops to turn in the opposite direction, the angle between the chain and the vertical is 1 degree less. How many times did the swing pass the vertical position before it stopped? What amount of degrees did it move through from beginning until it stopped?

Question 87246: the lengths of sides of a right angled triangle are respectively 6-x,13-x and 14-x.calculate the lengths of the sides.
let the sides of the triangle be =a,b,&c a=14-x , b=13-x &c=6-x
a^2=b^2+c^2 (14-x)^2=(13-x)^2+(6-x)^2
196-28x+x^2= 169-26x+x^2+36-12x+x^2
=x^2+x^2+169+36-26x-12x-x^2+28x-196
= x^2+205-196-38x+28x
= x^2-10x+9
x^2-10x+9=0 (x-9)(x-1)=0 x-9=0 x=9 or x-1=0 or x=1
therefore if x=9 then a=14-9=5,b=13-9=4 &c=6-9=-3
if x=1 then a=14-1=13, b=13-1=12 &c=6-1=5
