Which Law would you use to find

Q: Consider a right triangle with two other angles A and B.  Find the value of sin (A) if cos (A)=3/5?

A:

Q: 9) cos e 270

A:

Q: A+B+C = 180° then Sin At SinB+ Sin C = cotA cot B Sin A+ SinB Sin C 2. show that.

A:

Q: cos x = sin x tan² x cot³ x

A: To prove:- cosx=sinxtan2xcot3x

Q: () V3 i) tan 3 c) sin- cos

A: (c) sin-1(12) = π6this is in quadrant 1

Q: 4. Simplify, using the double-angle formulas: 1-2 sin² (15⁰)

A:

Q: The diagram below shows a right triangle that has side lengths of 6.03 and 2.91 cm and interior…

A: We need to find the angle in radians and degree.

Q: The point (2, 3) is on the terminal side of angle e, in standard position. What are the values of…

A:

Q: sin 280 cos 160 - cos 280 sin 160. Express the following as a function of a single angle.

A: Here we have to exprees the function in a single angle.

Q: Use the half-angle formula to find the exact value sin (π/8)

A: Trigonometry
