HELP!! I'm not sure what goes in the blank.

natta225 [31]

Answer:

10 $sin^{2} ($ β $)$

Step-by-step explanation:

We can find this two ways, first by seeing in the step after it, cosines are canceled out. Since you already have 10 $sin^{2} ($ β $)$ on the next step, you can assume that (since only the cosines changed and the cosine next ot the blank was removed), the value is 10 $sin^{2} ($ β $)$ .

You can also use double angle formulas from the previous step:

(sin(2β) = 2 sin(β) cos(β))and find that:

5 sin (2β) sin(β) = 5 * (2 sin(β) cos(β)) sin(β)) = (10 sin(β) sin(β)) cos(β) =

10 $sin^{2} ($ β $)$ cos(β)

But since cos(β) is already present, we can see that the answer is 10 $sin^{2} ($ β $)$

If a triangle has three unequal sides, what is true about the angles of the triangle?

rusak2 [61]

Answer:

Bro lemme tell you the real answer

Step-by-step explanation:

The answer is C and I actually have proof. You said that the triangle has 3 unequal sides. This means that it is a scalene triangle. Scalene triangles do not have any equal angles

Still dont believe me?

Heres a picture

In the picture the sides are unequal. The angles are therefore unequal
