Answer:
1. an isosceles triangle is a triangle that has two sides of equal length and two base angles that are equal. Also the sum of the interior angles of a triangle is 180°.
Therefore the base angles of the triangle as the information given and depicted above are 35°. The vertex angle is equal to 180° minus the two base angles.
vertex angle = 180° - (2 x 35°) = 180° - 70° = 110°
The answer is the measure of the vertex angle is 110°
2. The answer for number 2 is on the picture
