Question

In an isosceles triangle, the vertical angle is 15 degrees greater than each of its base angles. Find all the angles of the triangle

Answer 1

Answer:

55, 55 , 70 degrees

Step-by-step explanation:

in an isosceles triangle, the base angles are equal. let them be x degrees each

then the vertical angle= x+15 degrees

we know that sum of anles of a triangle= 180 degree

x +x+x+15=180

3x+15=180

solving equation we get x=55 degree

so the angles are 55, 55 & 70 degrees
