Something that you should remember is that the sum of the angles of a triangle add up to 180°.
Since we are given 100° and that the other two angles are equal, we can set up an equation like this:
, where x is the 2 angles.
Doing the math, the measure of each unknown angles is 40°.
Answer:
Step-by-step explanation:
we know that
If line l is parallel to line m
then
-----> by supplementary angles (consecutive interior angles)
solve for x
