Answer:
Step-by-step explanation:
The complete question in the attached figure
we know that
When two lines are crossed by another line (transversal), a pair of angles on the inner side of each of those two lines but on opposite sides of the transversal, are called <em><u>Alternate Interior Angles</u></em>.
When the two lines being crossed are Parallel Lines the Alternate Interior Angles are congruent
In this problem
---> by alternate interior angles
we have
therefore
Step-by-step explanation:
From the point -10 to -4, there is a difference of 6 units. Base = 6
From the x-axis to the furthest point, there is a difference of 6 units. Height = 6
6*6 = 36
36/2 = 18
Area = 18
