Given that is an isosceles triangle, where , determine the measures of and .
Step 1: Find the measure of .
If two sides of a triangle are congruent, then the two angles
opposite to those sides are congruent. Since , then
Write an equation to show that the sum of angles for
is . Let represent
and , and solve for the value of .
Step 2: Find the measure of .
and form a straight angle
