Answer:

see explanation

Step-by-step explanation:

m and 64° lie on a straight angle and are therefore supplementary, hence

m = 180 - 64 = 116

The sum of the 4 angles in a quadrilateral = 360°

Sum the angles in the quadrilateral and equate to 360

89 + 50 + 116 + n = 360 ← simplify left side

255 + n = 360 ( subtract 255 from both sides )

n = 105

Thus m = 116 and n = 105

Which of the following are solutions to the equation sinx cosx = (sqrt of 3)/4? Check all that apply.

Dmitriy789 [7]

$\sin x \cos x = \dfrac{\sqrt 3}{4}$

$2 \sin x \cos x = \dfrac{\sqrt 3}{2}$

$\sin 2x = \sin \frac \pi 3$

$2x = \frac \pi 3 + 2 \pi n \textrm{ or } 2x = (\pi - \frac \pi 3) + 2 \pi n \quad \textrm{integer } n$

$x = \frac \pi 6 + \pi n \textrm{ or } x = \frac \pi 3 + \pi n$
