Use cosine law to solve the problem. See image attached.
What we're looking for is the length of side A (a side which is opposite with angle A).
This is the formula of cosine law
A² = B² + C² - 2BC cos A
Input the numbers
A² = 75² + 90² - 2(75)(90) cos 85°
A =
A =

Answer:
$344.04
Step-by-step explanation:
The markdown multiplies the price by (1 -40%) = 0.60.
The tax multiplies the price by (1 +10%) = 1.10.
The two factors applied to the price make the final price be ...
$521.28·0.60·1.10 = $344.04
The total cost of the surfboard was $344.04.
