21 is 84% of 25
Convert the percentage (84) into a decimal by dividing it over 100:
Divide 21 over 0.84:

This is the formula for slope between two points:
so...
4
The slope is 4
Hope this helped!
so... that's how much an internal angle is
now, subtract that from 180 and you get the angle outside, in the picture
subtract that outside angle twice from 180, and you get angle "2"
because angle 2 is in the same triangle as those two outside angles, and all internal angles in a triangle is 180, thus 180 - (those two angles) is angle "2"
