Example Question #361 : Sat Subject Test In Math Ii
Suppose a set of intersecting lines. If an angle is 120 degrees, what must be the sum of the adjacent angle and the vertical angle to the given angle?
In an intersecting pair of lines, recall that vertical angles will always equal.
The adjacent angle with the given angle will form a straight line, and both of the angles must sum to 180 degrees.
Subtract 120 from 180 to get the adjacent angle.
Sum the two angles.
The answer is:
Example Question #11 : Finding Angles
If a set of angles are supplementary, what must be the other angle if a given angle is ?
Supplementary angles must add up to 180 degrees.
To find the missing angle, subtract the known angle from 180 degrees.
The answer is:
Example Question #12 : Finding Angles
If two angles of a triangle are radians, what must be the other angle in degrees?
Every pi radians equal 180 degrees.
We can choose to convert the radians to degrees first.
The sum of these two angles are:
Subtract this value from to determine the third angle.
