Sin60 = X/10√ ̅3
X=15 cm
And in triangle: (10√ ̅3)^2 = 15^2 + y^2
Y=√ ̅75= 5√ ̅3
The answer is D

okay thnks I will have a look into it
I think I might hav the answer... but is “and” supposed to represent “plus” or is it a separate question?
Answer:
b. 11 apples; 1 orange
Step-by-step explanation:
We test each option, and see if the total is $3.50(what you spend). If the result is different, it is not a possible solution.
a. 1 apple; 11 oranges
1 apple for $0.20
11 oranges for $0.30 each
0.20 + 11*0.30 = $3.50
Possible solution
b. 11 apples; 1 orange
11 apples for $0.20 each
1 orange for $0.30
11*0.2 + 0.3 = 2.5
Not $3.5, so this is not a possible solution.
This is the answer
c. 7 apples; 7 oranges
7*0.2 + 7*0.3 = $3.5
Possible
d. 4 apples; 9 oranges
4*0.2 + 9*0.3 = $3.5
Possible
Answer:
Step-by-step explanation:
we have 4x-3y=12
-3y=-4x+12
-y=-4x+12/3
we have 12=3*4 so we remove 3 that is up and 3 that is down
-y=-4x+4
then we get y=+4x+4
