I would say an answer to this does not exist. I cant see any relation between these terms.
The value of x is 21√2/2
The correct option is (A)
<h3>What is Trigonometry?</h3>
Trigonometry is a branch of mathematics that studies relationships between the sides and angles of triangles.
In triangle having angle 60.
sin 60 = P/ 7√3
√3/2= P/7√3
2P= 21
P= 21/2
Now again
cos 45= 21/2/x
1/√2 = 10.5/x
x= 21√2/2

Answer:
Bill spent $988 on taxes.
Step-by-step explanation:
First, you have to find the total amount that Bill spent last month on taxes and groceries as the statement says that he spent 40% of the total amount on that:
$6,000*0.4=$2,400
Then, the statement indicates that the total amount Bill spent on taxes was 70% of the amount he spent on groceries.
Let's consider that:
x=taxes
y=groceries
With the information we can write the following:
x+y=2,400 (1)
x=0.7y (2)
You can replace 2 in 1:
0.7y+y=2,400
1.7y=2,400
y=2,400/1.7
y=1,412
Then, you can replace the value of y in 2:
x=0.7(1,412)
x=$988
According to this, Bill spent $988 on taxes.
