Answer:
<em>The measure of the angle ∠ABC is 108°</em>
Step-by-step explanation:
<em>An isosceles triangle has two equal sides and two equal angles</em>
<em>In this problem</em>
<em>∠BDA=∠BAD= 66° ----> the angles of the base are equals</em>
<em>Find the measure of the vertex angle</em>
<em>∠ABD = 180° - 2×66° = 48° (the sum of the internal angles of a triangle is equal to 180°)</em>
<em>then. Find the measure of the angle ∠CBD in the equilateral triangle we know that</em>
<em>The measure of the internal angle in a equilateral triangle is 60° so</em>
<em>∠CBD= 60°</em>
<em>Then find the measure of the angle ∠ABC</em>
<em>∠ABC=∠ABD+∠DBC</em>
<em>substitute the values</em>
<em>∠ABC= 48°+60° = 108°</em>
<em>The answer is 108°</em>
<em>The measure of the angle ∠ABC is 108°</em>
