Answer:
fourth number is 9
Step-by-step explanation:
let 'x' equal the fourth number
(5+7+7+x)/4 = 7
cross-multiply to get:
19 + x = 28
x = 9
The answer is 48 degrees because you add 42 and 90 and then subtract from 180 (total degrees of a triangle)
2,000 + 400 + 70 would equal 2,470.
The correct way to write it would be 2,000 + 400 + 7
