Question

If two angles of a triangle are 0
30 and 0
80 , find the third angle.

Answer 1

Answer:

70°

Step-by-step explanation:

Let the third angle be x

30°+80°+x= 180° (Angle Sum Property)

110°+x = 180°

x = 180°-110°

x = 70°

Answer 2

Sum of triangle = 180°

30 + 80 + x = 180

x = 180 -110

x = 70 Answer

the third angle is 70°
