Step-by-step explanation:

5=x and -6=y so 5+-6 or 5-6=-1 so it makes the first equation true. Then plug it in to the second equation. (3)(5)--6 or (3)(5)+6 which = 15+6. 15+6=21. So both are true. Btw Im new to this hope this helps!

If sin(6m-8) = cos (2m), find the value of m.

Gala2k [10]

We believe that the angles are in quadrant 1.

<span>sin(6m-8) = cos (2m)

</span>⇒ 6m-8 = 90 - 2m
<span>
6m + 2m = 90 + 8

8m = 98

m = 98 / 8 = 12.25
