Answer:
sin(x) = -sqrt2/2
tan(x) = -1
Step-by-step explanation:
Because it is between 270 and 360, sin is negative, so it is -sqrt2/2.
tan(x) is sin(x)/cos(x), so it is just -1.

Answer:
319
Step-by-step explanation:
because 10 + something = this
Cosine = adjacent / hypotenuse
cosine (A) = 6 / 10
cosine (C) = 8 / 10
Since 8 / 10 equals 4 / 5 then it is
Angle C that is the answer
