Ray BD bisects angle ABC. The measure of angle ABD is represented by 4x-4 and the measure of angle ABC is represented by 7x plus 4. Find the measures of angle DBC.?
Angle ABD = 4x - 4 Angle ABC = twice angle ABD = 7x + 4 So 7x + 4 = 2*(4x - 4) = 8x - 8 So x = 12 Then angle DBC = half of angle ABC = 1/2*(7*12 + 4) = 1/2*88 = 44 degrees.
What is the complement of a 12 degree angle?
78 degree angle
What angle measures 95 degrees?
Uh, the answer is a 95 degree angle.... If the question is what type, a 95 degree angle is an obtuse angle >90 degrees and <180 degrees
What is the angle that measure that is complementary to the angle 78 degrees?
90-78 = 12 degrees
One exterior angle of a regular polygon measures 30 what is the sum of the polygons exterior angle measures?
If the exterior angle is 30o then the shape has 360/30 = 12 sides. An interior angle = 180 - exterior angle = 180 - 30 = 150. Since the shape has 12 sides the interior angles sum to 150 x 12 = 1800o.
What is the percentage slope of a 4 12 roof pitch?
The angle of inclination off horizontal is roughly 18-1/2o.
Can you show a 130 angle?
Yes, I can.It is the angle between the hour hand and 12 when the time is 4:20Yes, I can.It is the angle between the hour hand and 12 when the time is 4:20Yes, I can.It is the angle between the hour hand and 12 when the time is 4:20Yes, I can.It is the angle between the hour hand and 12 when the time is 4:20
How do you calculate a roof pitch of 6 degrees?
A roof angle of 6 degrees = 1.26 / 12 rise or pitch.
How do you calculate a 7.5 over 12 pitch into degrees?
This needs use of trigonometry. A pitch of 7.5/12 = 0.625 This means that the tangent of the angle is 0.625 Using trig tables or calculator, find the angle whose tangent is 0.625 The answer is 32 degrees

How do you figure out the pitch of a roof?
The angle, or pitch, of a roof is calculated by the number of inches it rises vertically for every 12 inches it extends horizontally.
Calculate pitch of roof?
Roof pitch is rise and run. So if you have a 4/12 pitch, for every foot of run the roof rises 4 inches.
Height of a 20' 4-12 pitch rafter?
3' 4"
What is pitch angle?
the angle of up or down
What is the angle pitch?
the angle of up or down
What is the measure of an interior angle of a regular polygon of 12 sides?
There is a formula which can help.The sum of the interior angles of a polygon is 2n - 4 right angles.When n = 12 then the interior angles total (2 x 12) - 4 = 24 - 4 = 20 right angles.Then for a regular polygon, each angle measures (20 x 90) / 12 = 150°.When the polygon is a regular polygon then it is perhaps quicker to calculate the external angle from which the interior angle can then be determined.Exterior angle = 360 /12 = 30°Interior angle = 180 - 30 = 150°
How do you measure the pitch on a roof?
Roof pitch is measured in "rise over run". In other words, how many inches does the roof rise vertically in 12" of horizontal run. If a roof rises 4" in 12" of run, you have a 4/12 roof pitch.
