Answer:

Step-by-step explanation:

Given that:

sin2xcos x + cos2xsin x = -1

Recall that;

SInAcosB + cosASinB = SIn (A+B)

SIn (2x +x) = -1

Sin (3x) = -1

$x = \bigg [\dfrac{Sin ^{-1} (-1)}{3} \bigg ]$

$x = \dfrac{\pi}{2} + \dfrac{2 \pi \ k}{3}$

$x = \dfrac{\pi}{2}, \dfrac{7 \pi}{6}, \dfrac{11 \pi}{6}$

What I did for this question is I set up ans equation. 5x-7 + 3x+11 = 180 and I added the Xs and and I added 11 to -7. Then I got 8x+4=180. I then "-4" on both sides and then divided 8 by 176. Getting X as 22. We now know X and we put 22 into the equation for D which is "3x+11" getting 77 degrees. Hope this helped!
