Answer:
sometimes, if their average angle is over 45 degrees
never are 2 obtuse angles summing to 180 degrees
always. two 90 degree angles always sum to 180 which is a straight line
6 because it is the GCF. 36/6 is 6 and 30/6 is 5
All of these angles can be compared to each other.
There are:
- Alternate interior angles
-- Angles that share one line and two parallel lines and are less than 90 degrees (angles 10, 12). These angles are equal to each other.
- Alternate exterior angles
-- Angles that share one line and two parallel lines and are more than 90 degrees (angles 1,5) These angles are equal to each other.
- Vertical Angle
-- Angles that share a point and are opposite of that point (angles 2,3) These angles are equal to each other.
-Supplementary angles
-- Angles that are on the same side of one line and share the side of another (angles 9,10). These angles are always equal to 180 degrees.
Using this we know:
a. m of angle 5 = to the m of angle 3 = 102
m of angle 5 = 102 degrees
Answer:
C
Step-by-step explanation:
The secant- tangent angle MLK is half the difference of the intercepted arcs, that is
(KN - KM) = 70° ( multiply both sides by 2 to clear the fraction )
KN - KM = 140°
KN - 61° = 140° ( add 61° to both sides )
KN = 201° → C
