Example Question #23 : Supplementary Angles
Suppose two angles are supplementary. If one angle is degrees, what must be the other angle?
Supplementary angles must add up to 180 degrees.
Subtract the known angle from 180.
The answer is:
Example Question #24 : Supplementary Angles
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 #25 : Supplementary Angles
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, has a measure of , thus we can write the following:
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 . So, we can use the formula:
where x and y are the angles.
So, given the angles
we can see one angle is . So, we can substitute and solve for x. We get
Example Question #515 : 2 Dimensional Geometry
If two angles are supplementary, and their angles are and , what must be?
The two angles must sum up to 180 degrees.
Add 10 on both sides.
Divide by 5 on both sides.
The answer is:
Example Question #1482 : Ged Math
Two angles are supplementary. If one angle is , find the value of the other angle.
Two angles are supplementary if they add up to . We can use the formula:
where x and y are the angles.
Now, we know one angle is . So, we can substitute and solve for the other angle. We get
Example Question #31 : Supplementary Angles
If an angle is 168 degrees, and both angles are supplementary, what must be the other angle?
Supplementary angles will add up to 180 degrees.
To find the missing angle, we will need to subtract the known angle from 180 degrees.
The answer is:
Example Question #32 : Supplementary Angles
If two angles are supplementary and one angle is measured in degrees, what is the other angle?
Supplementary angles sum up to 180 degrees. This means the other angle can be determined by subtracting the given angle from 180.
The answer is:
Example Question #31 : Supplementary Angles
If a set of angles are supplementary, and both angles are and , what must be the value of ?
The sum of a set of supplementary angles must add up to 180 degrees.
Divide by two on both sides to determine what is.
The value is:
