Sin 60 = opposite/hypotenuse

opposite is 30. Hypotenuse is what we are looking for. Use algebra:

hypotenuse = opposite/sin60

hypotenuse = 30/(sqrt(3)/2)
hypotenuse = 60/sqrt(3) = 60sqrt(3)/3 = 20sqrt(3)

So the belt is 20sqrt(3) or 34.6 foot

Step one:
ALWAYS set equation equal to zero, which in this case has already been done for us.

Step two:
Figure out what formula you need to use in order to solve in this case I'd use the Quadratic formula.

a=1
b=9
c=2

Quadratic formula:
$x = \frac{ - b + - \sqrt{(b) ^{2} - 4(a)(c)} }{2(a)}$
Then you would plug in the information.
$x = \frac{ - 9+ - \sqrt{(9) {}^{2} - 4(1)(2) } }{2(1)}$
The solve for what is underneath the square root ONLY.
$x = \frac{ - 9 + - \sqrt{73} }{2}$
Since you cannot solve this any further, your final two answers are...
$x = \frac{ - 9 + \sqrt{73} }{2}$
$x = \frac{ - 9 - \sqrt{73} }{2}$

the phone costs £140 and then you pay for a one year contract at £15 per month. how much do you pay in total at the end of the y

Karolina [17]

At the end of the year, you pay 320 dollars.Just multiply 15 by 12, and add the sum to 140. Hope this helps!
