The given triangle is a right-angled triangle. This means that special trig identities can be applies

These identities are as follows:

sin (theta) = opposite / hypotenuse

cos (theta) = adjacent / hypotenuse

tan (theta) = opposite / adjacent

Now, for the unknown theta in the triangle:

The opposite side is 16 and the hypotenuse is 20

This means that we will use the sin not the cos as Bob did

The solution will be as follows:

sin (theta) = opposite / hypotenuse

sin (theta) = 16 / 20

theta = sin^-1(16/20)

theta = 53.13°

Hope this helps :)

Kurt is buying a watch that had an original price of $195 but is advertised as 35% off. Sales tax of 8.75 % is applied to the di

Schach [20]

Answer:

$137.84

Step-by-step explanation:

We have been given that Kurt is buying a watch that had an original price of $195 but is advertised as 35% off. Sales tax of 8.75 % is applied to the discount price. We are asked to find the amount paid by Kurt for the watch.

First of all, we will find discounted price of watch by calculating 65% of original price as 100% minus 35% is 65%.

$\text{Discounted price of watch}=\$195\times \frac{65}{100}$

$\text{Discounted price of watch}=\$195\times0.65$

$\text{Discounted price of watch}=\$126.75$

Now we will add 8.75% of $126.75 to $126.75 to find price of watch after sales tax.

$\text{Price of watch after sales tax}=\$126.75+\$126.75\times \frac{8.75}{100}$

$\text{Price of watch after sales tax}=\$126.75+\$126.75\times 0.0875$

$\text{Price of watch after sales tax}=\$126.75+\$11.090625$

$\text{Price of watch after sales tax}=\$137.840625$

$\text{Price of watch after sales tax}\approx \$137.84$

Therefore, Kurt will pay $137.84 for the watch.
