Answer:
C}
Step-by-step explanation:
Use the tangent ratio here: tan(18) = x / 4...4 tan(18) = x, and x = 1.30
5x+6 + 9x+2=360
5x+9x= 360-6-2
14x÷14=352÷14
x=25.14
Answer:
Um ig... which problem?
Step-by-step explanation:
C(n,r) =n!/(r!(n-r)!)
c(n,r)= c (40,16)
= 40!/(16!(40-16)!)
=6.2852101650+10
=62852101650
