The 1998 team payroll of the Baltimore Orioles was $68,988.134. (Source: Major
Gekata [30.6K]
False. This is not a statistic. A statistic would be something more like “Since 1998, the team payroll of the Baltimore Orioles increased 26%” Statistics show things more overtime, rather than that just being a basic fact that the team payroll was that amount.

Helppppp! please show your work!
Shtirlitz [24]

Answer:

90 - 37 will give a solid 53

Step-by-step explanation:

the two sums of A to C to C to B so 22.9(C, B) and 14.1 (A, C)

and know that this angle is 90 degrees, my guess would be to subtract the to given numbers with degrees to earn the sum so 22.9 + 14.1 equals 37

now we add angle degrees and sum and subtract one another,

90 - 37
