Answer:
Step-by-step explanation:
Note: For this problem we use the calculator on degrees
For this case we need to remember this identity :
For this case if we apply for our desired formula we got this:
And we want this equal to so we can set up the following equality:
(1)
If we apply direct comparison between the factors on equation (1) we see this:
(2)
(3)
If we solve a from equation (2) we got:
(4)
If we replace equation (4) into equation (3) we got:
If we apply inverse tangent on both sides we got:
So then the value of c= 36.870 degrees. And since w ehave the value of c we can find the value for a and we got:
And then our expression in the form is:
And we can check that:
