Question

one of the two equal angles of an isosceles triangle measures
55 degree . Determine the other angle​

Answer 1

Answer:

the other angle = 70 degrees

Step-by-step explanation:

the sum of all angles in a triangle is equal to 180degrees

give that the one angle of 2 equal angles=52 degrees. .we know that in a isosceles triangle the 2 angles are equal ..let the other as =x

so 55+55+x=180

110+x=180

x=180-110=70

therfore x=70degrees
