Supplementary angles.
This is because supplementary angles are two angles that add up to 180 degrees, and these two angles would add up to 180 degrees.
Answer: Its D :)
Step-by-step explanation:
In this question, it is given that An inverse trigonometric function is used to find the value of an unknown obtuse angle in a triangle. The inverse function returns the angle 68°.
Since the angle is obtuse angle, it means the measurement of the angle is greater then 90 degree. And to find the angle measurement, we have to subtract the given angle from 180 degree.
So the unknown angle is

And that's the required answer .
Answer:
y=1/3x -4
Step-by-step explanation:
3y-x=-12
y= 1/3x-4
m=1/3
(gradient is the same since its parallel)
y=mX+c
(2) = 1/3(18) + c
2 = 6 + c
2 - 6 = c
c= -4
(y-intercept)
Therefore: y=1/3x-4
