Answer:
XW = 4 units
Step-by-step explanation:
Given tanf° =
, then
tanf° =
=
=
=
( cross- multiply )
2XW = 8 ( divide both sides by 2 )
XW = 4
Answer:
12
Step-by-step explanation:
To find the mean, add up all the numbers
18+ 19+ 19+ 4+14+ 8+ 22+ 3+ 1
108
Then divide by the number of terms
108/9 =
12
Answer:
