Answer:
X = 18
Y = 9√3
Step-by-step explanation:
use sin equation for right angle triangle
The sine of the angle
= ( the length of the opposite side ÷ the length of the hypotenuse.)
according to this question,
sin 30 = 9 / X
1/2 = 9 / X
X = 18
use cosine to find y
The cosine of the angle
= (the length of the adjacent side ÷ the length of the hypotenuse.)
cos 30 = y/x
√3/2 = y/ 18
y = 9 ✓3
Answer:
2:5
Step-by-step explanation:
Because if we look 8:20 can be turned into 8/20 and if we simply we got 2/5 and turn it into 2:5

Answer:
1.125
Step-by-step explanation:
the unit cost is how much it cost per wheel
dozen is 12
so 12 times 6 is 72
so then you do 81/72 to get your answer
and you are probably wondering how i got the divison from was because i'm supposed to divide to find a unit cost.
the 81 was the total for the 72 packages of toy wheels
