Vertical angles are always equivalent. Therefore, we know that if the first vertical angle measures 30 degrees, the other must measure 30 degrees as well. So, since the second vertical angle has a value of 3n-6, we can set this equal to 30 degrees yielding the equation 3n - 6 = 30. From here, we just need to do some simple algebra:
3n - 6 = 30
3n = 36
n = 12
To find the value of n.

What are angles that together measure 180 degrees?
A straight angle is an angle that measures 180 degrees and is drawn as a straight line. A straight angle is composed of two right angles whose measures are 90 degrees each.
What are all the angles in a regular hexagon called?
Exterior angles are acute because each angle measures 60 degrees Interior angles are obtuse because each angle measures 120 degrees
What is the exterior and interior angles of a regular 20-gon?
Exterior angle measures 18 degrees Interior angle measures 162 degrees
If one angle of a parallelogram measures 40 degrees and another angel measures 140 degrees what are the measures of the other two angles?
The other two angles are also 40 degrees and 140 degrees.
In a right-angled triangle besides the right - angle one of the angles measures 30 degrees what does the other angle measures?
60 degrees. There are 180 degrees in a triangle.
What is the sum of the measures of the interior angles of a regular polygon if each angle measures 90 degrees?
If each angle measures 90 degrees the polygon is a square and so its angles sum to 360 degrees.
If angle B measures 42 degrees and angle C measures 27 degrees what is the measure of angle A?
If the angles A, B and C forms a triangle, then angle A is 111 degrees.

The other two angles are also 40 degrees and 140 degrees.
What has an angle that measures 90-180 degrees?
270
What an angle which measures 90 degrees?
A right angle. A square has 4 right angles.
In a right-angled triangle besides the right - angle one of the angles measures 30 degrees what does the other angle measures?
60 degrees. There are 180 degrees in a triangle.
Are reference angles and radians the same?
No. A radian is a measure of an angle, it is not, itself, an angle. Degrees and radians are measures of angles and the two measures are related by the following conversion: 180 degrees = pi radians
What is one of the angles on a regular 20-gon?
Each exterior angle measures 18 degrees Each interior angle measures 162 degrees
What are two angles that have the same measures have the sum of 90?
Two angles that have the same measure and sum up to 90 degrees are complementary angles. For example, if one angle measures 45 degrees, the other angle will also measure 45 degrees, and their sum will be 90 degrees.
