Remark
The diagram is a mess of lines; you have to guess where that 12 belongs. Just to make the question a bit more interesting, I'm going to say the 12 belongs to the perpendicular.
If that's true you can find KT using Pythagorus. KT and RT are equal. (SSS)
So, let's go.

1/2 of ST = 1/2 32 = 16
12 is the leg of the small triangle KT and the third point where the perpenduclar line meets ST.
Solution
KT^2 = 16^2 + 12^2
KT^2 = 256 + 144
KT^2 = 400
KT = sqrt(400)
KT = 20
RK = KT because parts of a congruent triangle = parts of the other triangle containing the line (KT) that you are trying to find the length of.
Answer:
Step-by-step explanation:
The standard way of writing equation of a line in a point-slope form is as given;
y - y0 = m(x-x0)
m is the slope of the line
(x0,y0) is a point on the line.
Given the point (-2,-6), in order to determine with of the equation that correctly uses the point, we will substitute the point into the formula and get the necessary equation.
y - y0 = m(x-x0)
y - (-6) = m(x-(-2))
y+6 = m(x+2)
Since we are not given the slope, let's assume the slope is 5/2
The equation becomes y+6 =5/2(x+2). Option D is correct

so toal cost=28 right?
total cost=total cost of water+total cost of tickets
water=3
subsitute 28=total cost and 3=total cost of water
28=3+total cost of tickets
remember we can do anything to an equaton as long as you do it to both sides
28=3+total cost of tickets
subtract 3 from both sides
28-3=3-3+total cost of tickets
25=0+cost of tickets
25=cost of tickets
if he bought 5 tickets, how much does each cost
25=5tickets
divide both sides by 5
25/5=5/5tickets
5=1tickets
answer is 1 ticket cost $5.00
equation is
total cost=water+tickets
28=3+5tickets

The two heaviest pumpkins weigh 19.5 lbs. Together, they weigh 35 lbs.
The two lightest pumpkins weigh 10 lbs and 10.75 lbs. Together, they weigh 20.75 lbs.
35 - 20.75 = 14.25 lbs
Hope this helps!
