Answer:
Step-by-step explanation:
The figure shows a right triangle.
To calculate the measure of the angle A, you can use the inverse trigonometric function arctangent:
Identify the angle 
, the opposite side and the adjacent side:
Substitute into .
The measure of the angle A is:

Answer:
n=3
Step-by-step explanation:
you have 2n+7=6n-5
start with subtracting 2n from both sides giving you 7=4n-5
now take the -5 and add 5 to both sides, giving you 12=4n
now divide both sides by 4, now giving you 3=n
the variable has to be on the left every time you finish your work living with n=3
Answer:
264 ft/sec
Step-by-step explanation:
We need to use the conversion factors
5280 ft/ 1 mi, 60 min/ 1 hr , and 60 sec/1 min
180 miles 1 hour 1 min 5280 ft
----------------- * ----------------- * ------------ * ---------------
hour 60 minutes 60 sec 1 miles
The hours, minutes and miles cancel are we are left with ft/sec
180 *5280 ft
----------------- * -----------------
60*60 sec
264 ft/sec
X is equal to 50 in this equation.
I believe that angle 6 is 108 because I drew to the best of my ability and I see that 3 and 6 are alternate interior angles.
