Final answer:
To find the value of x in the given case, we need to use the properties of parallel lines and isosceles triangles. Since hm is parallel to dg, we know that the corresponding angles are congruent. Therefore, m∠cab = m∠cba = x.
Step-by-step explanation:
To find the value of x in the given case, we need to use the properties of parallel lines and isosceles triangles. Since hm is parallel to dg, we know that the corresponding angles are congruent. Therefore, m∠cab = m∠cba = x. In an isosceles triangle, the base angles are congruent, so m∠cab = m∠cba = x. Therefore, the value of x is the measure of these angles.
