What you need to do is divide 32 by 40 so you end up with 1%. Then you need to multiply that by 25 and you will get 25%
32÷40=0.8
0.8x25=20

Step-by-step explanation:
Okay so this won't be the easiest for me to explain by typing but i'll do my best
this is a geometry question. a couple important things to know are as follows:
1) all of the quadrants should add up to ninety because two of the lines crossing eachother have a 90 degree square.
2) every angle diagonal from another one are the same. so if two lines cross in an X shape, the top angle and the bottom angle are equal and the two side angles are equal.
so now we're ready to start.
let's start with angle N. it will be easiest.
using the rule of the diagonals, you'll notice that N is diagonal to the 90° square therefore it too is 90°
N = 90°
next, angle M. using the diagonal rule, the angle across from the 15° is going to also be 15°, that means that that quadrant has an angle of 40° and 15°. now recall that all the quadrants must add up to 90°. so from this we can make a simple equation:
40° angle + 15° angle + M angle = 90°
now solve for M angle
40 + 15 + M = 90 55 + M = 90 M = 35°
so N = 90° and M = 35°
Answer:
8.28 units
Step-by-step explanation:
The formula for the circumference of a circle is 
where
is the circumference of the circle
is the diameter of the circle
We know form our problem that the circumference of our circle is 26.28 units, so 
. Let's replace that value in our formula and find :
Divide both sides of the equation by 
The diameter of the circle that has a circumference of 28.26 units is 8.28 units.
