The vertex angle of an isosceles triangle is equal to the measure of each of its base angles. Therefore, if one of the base angles measures 42 degrees, then the vertex angle also measures 42 degrees.

the sum of the measures of the interior angles of any triangle equals 180*. the two base angles in an isoceles triangle are equal to each other so if you have the measure of one of the two base angles, then you know the other. so for example, if one base angle equals 36, then the equation to find the missing angles would be 36+36+x=180 when solved x=108, which would be the non base angle

The vertex angle of an isosceles triangle is equal to the measure of each of its base angles. Therefore, if one of the base angles measures 42 degrees, then the vertex angle also measures 42 degrees.

As presented, the question cannot be answered. But if you assume - however unjustified such assumptions are - thatthe triangle is isosceles andthat these are the two base angles, thenthen each base angle is 74 degrees.

The measure of each base angle in an isosceles triangle can be calculated by dividing the total angle sum by the number of base angles, i.e., (180 - vertex angle) / 2. In this case, each base angle of the isosceles triangle would measure (180 - 38) / 2 = 71 degrees.
