Answer 1

Answer:

in isosceles triangle each base angle is 30° greater than the vertical angle find the measure of the all the three angles of the triangle

Answer 2

Answer:

Explanation: Notice that in an isosceles triangle there are at least two congruent angles. Also, as in all triangles, the sum of the angles is 180° . We can then solve for x and determine that 3x+60=180 , which leads to 3x=120 and finally x=40 , so the vertex angle is 40° and each base angle is 70° .
