1. N is a midpoint of the segment KL, then N has coordinates

2. To find the area of △KNM, the length of the base MK is 2b, and the length of the height is a. So an expression for the area of △KNM is

3. To find the area of △MNL, the length of the base ML is 2a and the length of the height is b. So an expression for the area of △MNL is

4. Comparing the expressions for the areas you have that the area
is equal to the area
. This means that the segment from the midpoint of the hypotenuse of a right triangle to the opposite vertex forms two triangles with equal areas.
12, 4, 4/3 has a common ratio.
Answer:
Step-by-step explanation:
x+y=180; y+z=180
145+z=180
z= 35
y=180-35
y =145
x=180-145
x= 35
---------------------
2x-10=x+80
x=90
3y-4 =y+20
2y = 24
y = 12
The sold 45 digital cameras. So 45 out of 72. So you have to 8x9=72 and then 5x9=45 Then the answer would be 45!
Every time they are divided by 2
