Which equation can be used to find the length of ? (10)sin(40o) = AC (10)cos(40o) = AC = AC = AC
2 answers:
The answer:
ABC is a right triangle.
according to the figure, the length AC is the opposite side relative to the angle 40°,
for that, the main formula is
sin40° = opposite side / hypotenuse
opposite side =AC, and hypotenuse = 10 in
therefore, sin40° = AC / 10, and then AC = 10 sin40°
so for finding the value of AC, we can use AC = 10 sin40°

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%.
Now we will add 8.75% of $126.75 to $126.75 to find price of watch after sales tax.
Therefore, Kurt will pay $137.84 for the watch.
