1. 1.09392(10^5)
2. 1.1130(10^4)
hope this helps
The answer is 10:00 am
add 3 to 6 then add the 30 minutes to the 30 minutes which equals another hour
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 =
