and
respectively.
Step-by-step explanation:
The given trigonometric equation is
We divide both sides by to get,
This implies that,
We take the inverse tangent of both sides to get,
Since the tangent ratio has a period of , another solution is
to the nearest degree.
In the third quadrant,
The solutions are
The value of x that satisfies the equation if x lies in the second quadrant is
The value of x that satisfies the equation if x lies in the third quadrant is
Answer:
m∠2 = 140°
Step-by-step explanation:
m∠1 = m∠3, since they're vertical angles.
Solve for x:
Plug in 6 for x for either m∠1 or m∠3. Doesn't matter since they're equal.
m∠1 = (2(6) + 28)°
m∠1 = (12 + 28)°
m∠1 = 40°
Now that we know m∠1, we can now solve for m∠2.
m∠1 + m∠2 = 180°
40° + m∠2 = 180°
m∠2 = 140°
