Question

the vertical angle of an isosceles triangle is 135 degree. find it's base angles
please help me please​

Answer 1

Answer:

let the base angles be x each

Now we can write:

x+x+135=180 [sum of the angles of a triangle]

2x= 180-135

2x =45

x= 45/2

x=22.5

therefore base angle is 22.5° each

Answer 2

Answer:

twenty two point five because both sides are equal to each other
