Answer:

X=-9

Step-by-step explanation:

First, distribute the 2. So, it would be 2x-6+21=-3. Then, bring the -6 and 21 to the right side. It would now be 2x= -18. X would be equal to -9.

Hope this helps!

How do you solve (Arc)QPT if <QZT = 120

yuradex [85]

By definition, the arc length is given by:
arc = R * theta * ((2 * pi) / 360)
Where,
theta: angle in degrees
R: radio
We have then:
(Arc) QPT if <QZT = 120:
theta = 360-120 = 240 degrees
R = 13.5 units
Substituting values we have:
(Arc) QPT = R * theta * ((2 * pi) / 360)
(Arc) QPT = (13.5) * (240) * ((2 * pi) / 360)
(Arc) QPT = 56.55 units
Answer:
(Arc) QPT = 56.55 units
