Question

the base angle of anisosceles triangle is 55° the size of the vertical angle is​

Answer 1

Answer:

Here, in the question the two interior angles of the isosceles triangle are 55 degrees each. So, substituting the values in the equation x+y+z=1800 to determine the value of the vertical angle. Hence, the vertical angle of the isosceles triangle is 70 degrees.

100% Correct.
