Is there any way to add a screenshot instead of taking a picture?

on a laptop? on my mac, i click shift,command, and 4 at the same time, and then i drag the pointer thing to what i want screenshotted

b is 38 degrees.

a is 52 degrees.

this is because if b is 38 and a is 14 degrees more than b than 38+14=52 and 52+38=90 degrees. hope this .

what grade level is this? need to know so i can look in my old textbooks!
