Triangle A B C is shown. Angle A C B is a right angle. The length of hypotenuse A B is 12 centimeters, the length of C B is 9.8
centimeters, and the length of A C is 6.9 centimeters. Which expressions can be used to find m∠BAC? Select three options. cos−1(StartFraction 6.9 Over 12 EndFraction) cos−1(StartFraction 9.8 Over 12 EndFraction) sin−1(StartFraction 6.9 Over 12 EndFraction) sin−1(StartFraction 9.8 Over 12 EndFraction) tan−1(StartFraction 6.9 Over 9.8 EndFraction)

Answer:
<h2>First and Fourth choices are correct.</h2>Step-by-step explanation:
In the image attached you can observe the triangle described in the problem.
To find the measure of angle BAC, we just need to use trigonometric reasons. Notice that we already have all sides, so it doesn't matter which reason we use.
This means the first choice is correct.
The fourth choice is correct.
The last choice is not correct, because that option is showing the inverse of the tangent function.

Answer:
29 minutes
Step-by-step explanation:
Given
Required
Determine the number of minutes (t) that he was on the trampoline.
This can be expressed as:
Where t represents the number of minutes
Substitute values for Total, Entrance Fee and Amount per minute
Solving further to get the value of t, we have:
As given,
Loan amount is = $45000
Rate of interest = 8.5%
So, Tony's mortgage will attract an interest of:
= $3825 (this is yearly)
And for 1st month it will be = = $318.75
As given, the first month's payment is $390.60 and this covers the interest Additional amount ($390.60 - $318.75 = $71.85) is a payment against the principle.
Hence, the new principle after the 1st month is $71.85 less than $45000
= 45000-71.85 = $44928.15
Hence, the last option $44928.15 is the correct answer.
