You can use proportions.
22.5/100 = 18/x
cross multiply:
100 x 18 = 1800
1800/22.5 = 80
so now you know 80 is the 100%.
then do:
37.5/100 = x/80
cross multiply:
37.5 x 80 = 3000
3000/100 = 30
37.5% = 30
I you think about it 12a with the 2 on the rope is actually 144 because it’s multiplied by 12 so maybe that helps?
Answer:
the angle of 3 is 50
Step-by-step explanation:
What you would do is add 90 to 40 which would get you 130. Then you will subtract 130 from 180 which gets you 50 for angle 1. Since angle 1 is across from angle 3, angle 3 will also be 50.
