Answer:
.754
Step-by-step explanation:
Percentage is based off of 1 or 100% which is equal to 1. So 50% or half of both 100% and 1 would be translated as .5 and as the percentage becomes more accurate or lengthy you add to the decimal so 53% is .53 and 53.4% is .534
Answer: X=15 , Y=15
This triangle is a 30, 60, 90 so that means it would be - a, 2a, a on each side, so add that all together and you get x-15 and y-15
