Question

Two interior angles of a triangle are 30° and 70° find the third angle​

Answer 1

Answer:

260°

Step-by-step explanation:

let the third angle be x;

first angle= 30°

second angle= 70°

third angle= x

triangle= 360°

= 30° + 70° + x = 360°

= x = 360° - 30° + 70°

x = 360° - 100°

x = 260°

the third angle is 260°
