Question

two angles of a triangle measure 50 degree and 60 degree the measure of a third angle is is​

Answer 1

Answer:

70 degree

Step-by-step explanation:

We know that the sum of the angles of a triangle = 180 degree

Hence in this case, as the two angles are given we need to find out the third one

sum of the two given angles = 60+50 = 110 degree

let the third angle be x

therefore x+sum of the two given angles = 180 degree

therefore x = 180 - sum of the two given angles

therefore x = 180 - 110

     or       x = 70 degree

Answer 2

Answer:

the sum of all angle of triangle is equal to 180

so,let a+b+c=180

50+60+c=180

110+c=180

c=180-110

c=70

so the measure of a third angle is 70
