The fundamental equation of trigonometry states that
.
This derives from the fact that any point on the unit circle has coordinates , together with the fact that the equation of the unit circle is
So, from the fundamental equation you can deduce
which in your case leads to
Answer:
The answer is D.
Step-by-step explanation:
Distributive Property
4x3=12
4x7=28
28+12=40
Answer:
x=13
Step-by-step explanation:
180 is the total degree of any triangle. Divide by 3 and you get 60 degree angles. Subtract 8 and you gey 4x=52. Divide then to get 13
