Answer:
59
Step-by-step explanation:
do the adding up of all angles you will get a number greater than 59 and divide the number withh the amountt of angles there are which are 3 so divide the number by three and you will end up with 59 and thats the answer
Answer: 1 = 4.20, 2 = 8.40 3 = 12.60 4 = 16.80
This is a direct variation.
X^2 + 7x + 7x + 49 = x*(x+7) + 7*(x+7) = (x+7)(x+7) = (x+7)^2
