Question

two angle of a triangle are 30 degree and 80 degree find the third angle

Answer 1

Answer:

70 degree

Step-by-step explanation:

30+80+x=180(sum of interior angles of a triangle=180)

110+x=180

x=180-110

x=70

Answer 2

Answer:

70°

Step-by-step explanation:

a triangle has a total of 180°

so 80 +30 = 110

subtract the sum of the two angles from 180 to get the sum of the third angle

180 -110 =70
