Set up a ratio:
16/12 = 28/?
Cross multiply:
16? = 12 x 28
16? = 336
Divide both sides by 16:
? = 336/16
? = 21
Answer:
4.1
Step-by-step explanation:
Mean = sum/n
(1+2+10+6+4+4+6+3+1+4)/10
41/10
7%
30
see below
• find x
use tan rule
tan( 60 degrees) = x / 7
tan ( 60 ) x 7 = 12 . 1
x = 12. 1
• find y
you can either use Pythagoras theorem or the sin rule
let's use sin
sin ( 30 ) = 7 / y
y = 14.0
