The given measurements may or may not determine a triangle. if not, then state that no triangle is formed. if a triangle is formed, then use the law of sines to solve the triangle, if it is possible, or state that the law of sines cannot be used. c = 37°, a = 19, c = 8

According to the sin law,

For a triangle ABC,

In which AB, BC and CA are the edges of the triangle,

And, ∠ A , ∠ B and ∠ C are the angles of the triangle.

Here, AB = 8 unit BC = 19 unit and ∠ C = 37°

According to the sin law,

For triangle ABC,

⇒

⇒

⇒

Which is not possible.

Because -1 ≤ sin A ≤ 1

Thus, the triangle ABC can not be possible.

step-by-step explanation:

hello from mrbilldoesmath!

answer:

25x^2 + 90x + 84

discussion:

mn(x) = m(n(x)) = m( 5x + 9) =

(5x + 9)^2 + 3 =>

25x^2 + 90x + 9^2 + 3 =

25x^2 + 90x + 84                 (as 9^2 = 9*9 = 81)

which is the second choice
