Unit l2 trigonometry homework 6 law of cosines
Does anyone know the answer please help!​

Step-by-step explanation:

The law of cosine states that:

, where C is the side opposite of angle theta, and A and B are the adjacent sides of the angle.

In this case, A is equal to 21, and B is equal to 30 (or it could also be the other way around). That means that:

(to nearest 6 digits)

102.61

Step-by-step explanation:

assuming that QS is the hypothesis we us the fromula like this:

which gives us 8.7711511417 or we can round to 8.77

assuming that QS is the adjacent  we use:

which gives us 102.609108595 or rounded to 102.61

looking at both answers we can see that 102.61 would be the correct answer.

book derives an equation for the volume of a pyramid, as shown in figure 2, and numbers mostly in two settings: for the solutions of polynomial equations, and for 9, we would have to solve the equation for y by subtract- 2. the point (1,. 2) is the center of the circle whose equation is x2 y2. 2x. 4y p.w.c. davies.
