Answer:
θ = -33.69°
Step-by-step explanation:
For Φ>0 and Φ<0 (in general Φ≠nπ where n is an integer), sin(Φ) ≠ 0
Dividing both equations:

Therefore:
arctan(θ) = -2/3
θ = -33.69°
The answer does not depend on the sign of Φ, in fact we just need that the sine does not become zero, which occurs when Φ is equal to an integer times π (radians) or 180 (degrees)
Have a nice day!

5 cups of chocolate chips to 3 cups sugar
so the ratio of chocolate chips to sugar is : 5/3 or 5:3 or 5 to 3
given that - 1 hour = 60 min
then, 25 60
then, we cut it from the table of 5 !!
therefore, 5:12
It wouldnt be reasonable bc a scale factor of 1 would make no difference therefore meaning there is no dilation.
