4.1 = 4 1/10 = 41/10
The angles in a triangle must add up to equal 180. When it gives you angle A and angle B, you add them, then subtract it from 180, which will give you the angle C.
65 + 15 = 80
180 - 80 = 100 = Angle C.
It says to list them from smallest to greatest.
<B = 15, <A = 65, <C = 100
37.68m this is my best guess sorry if it's wrong :)
Divide 5/8 by 150, to see how thick each is, that'll give you 150 even pieces that add up to 5/8
