Example Questions
Example Question #506 : 2 Dimensional Geometry
Figure NOT drawn to scale.
Refer to the above figure. Evaluate 
The marked angles form a linear pair and are therefore supplementary - their degree measures total 
Simplify and collect like terms:
Subtract 88 from both sides:
Divide both sides by 2:
Example Question #1471 : Ged Math
If an angle is measured 75 degrees, what is the other angle if both angles are supplementary?
Supplementary angles sum up to 180 degrees.
To find the other angle, subtract the given angle from 180 degrees.
The answer is:
Example Question #22 : Supplementary Angles
Suppose the angle 
If two angles are supplementary, they must add up to 180 degrees.
Set up an equation such that both angles will add to 180 degrees.
Solve the equation.
Divide by 5 on both sides.
One of the possible angles is either 
The answer is:
Example Question #1472 : Ged Math
Two angles are supplementary if they add up to:
Two angles are supplementary if they add up to 
Example Question #24 : Supplementary Angles
Two angles are supplementary. If one angle is 
If two angles are supplementary, they add up to 
Now, we know one angle is 
Therefore, the other angle is 
Example Question #1473 : Ged Math
Suppose two angles are supplementary. If one angle is 
Supplementary angles must add up to 180 degrees.
Subtract the known angle from 180.
The answer is:
Example Question #1474 : Ged Math
If two angles are supplementary to each other, what is the other angle if one angle is 135 degrees?
Supplementary angles add to to 180 degrees.
To find the other angle, subtract the known angle from 180.
The answer is:
Example Question #1475 : Ged Math
Suppose two angles are supplementary to each other. What is the value of the other angle if one angle is measured 120 degrees?
Supplementary angles must add up to 180 degrees.
To find the other angle, subtract the known angle from 180.
The answer is:
Example Question #81 : Angle Geometry
In the diagram below, find the measurement of 
Notice that the three smaller angles all lie on a straight angle. This means we can write the following equation:
Now, 
Example Question #514 : 2 Dimensional Geometry
Use the following diagram of angles to answer the question:
If these two angles are supplementary, find the value of x.
Two angles are supplementary if they add up to 
where x and y are the angles.
So, given the angles
we can see one angle is
