Question

if in a triangle two angles are 77degree and 33 degree. then find third angle.​

Answer 1

Answer:

$third \: angle = 70$

Answer 2

Answer:

70 degree

Step-by-step explanation:

let the third angle be x

angle A= 77degree, B= 33 degree

sum of all angles of a triangle is 180 degree

A+B +c = 180

77 +33 + x = 180

110 +x = 180

x = 180 -110

x = 70

hence the third angle is 70 degree
