Question

The exterior angle of a triangle is 130⁰ and one of its interior opposite angles is 55⁰. The measure of other opposite interior angle is_____.

Answer 1

Step-by-step explanation:

angle of interior opposite angles = exterior angle

let the one interior angle be x°

second interior angle be 55°

and exterior angle be 130°

so according to the property

sum of interior opposite angle =exterior angle

55+x=130

x=130-55

x=75°

so, interior angle is 75°
