He for got his pin code. 20% of his pin code was 246.8. what was his pin code?

So if 20% of his pin code was 246.8, then we want to know 5 times that since 20% * 5 = 100%.

So 246.8 * 5 = 1234

So his pin was 1234.

C. i believe it is (5×(-20))+(100×(0.7))

Byou start by adding them all and setting them equal to 180 since that is half of the total degrees in a circle.(2x+8) + (3x-14) + (3x-14) = 1808x-20 = 1808x = 200x = 25
