Area of a triangle= 1/2 (ab) (sin C)
= 1/2 (9 x 11.5) (sin 63.4)
= 46.27

I believe the answer is cos^2 theta. Sec^2 theta on the right side of the equation is the inverse of Cos^2 theta, so multiplying the two together will get you 1. Cos^2 theta * Tan^2 theta = Sin^2 theta, and Cos^2 theta * 1 = Cos^2 theta. This all leads to the third and last step in the picture above.

Answer:

10. 0

11. -16

12. 2

13. 2

14. 3

15. 0

Step-by-step explanation:

10. (x+4)(x-4) --> x= 4, -4 --> 4 + (-4) = 0

11. 4(-4) = -16

12. 2(x-2)² --> x = 2

13. 2

14. x(x-3) --> x= 0, 3, 0+3=3

15. 0(3) = 0

Answer:

The angle between the 190 ft. side and the 330 ft. side is $57.9^o$

Step-by-step explanation:

The Law of Cosines

When we know the value of all sides of a triangle, we can compute all of its interior angles by using the Law of Cosines, which is a generalization of the Pythagoras's theorem. If a,b, and c are the known sides of a triangle and $\alpha$ is the angle formed by sides a and b (opposite to c), then
