Answer:

7 sqrt(2)

Step-by-step explanation:

We can use trig functions

sin theta = opposite side/ hypotenuse

sin 45 = 7/x

Multiply each side by x

x sin 45 = 7

Divide each side by sin 45

x = 7 / sin 45

x = 7 (sqrt(2) /2)

x = 14 / sqrt(2)

We do not leave square roots in the denominator

x = 14 / sqrt(2) * sqrt(2)/ sqrt(2)

   12 sqrt(2)/ 2

  = 7 sqrt(2)

$800 and paid 14% tax what was final bill
evablogger [386]

Answer:

$912

Step-by-step explanation:

First, find the tax.

Multiply the tax rate by the price.

tax rate * price

The tax rate is 14% and the price is $800.

14% * 800

Convert 14% to a decimal. Divide 14 by 100 or move the decimal places 2 spaces to the left.

14/100=0.14

14.0–> 1.4 —> 0.14

0.14 * 800

Multiply

112

The tax is $112.

Now find the total bill.

Add the tax and the price.

tax + price

The tax is $112 and the price is $800.

$112 + $800

Add

$912

The final bill is $912.
