Question

Calculate the third angle of a triangle in which two of the angles are 47 degrees and 65 degrees.​

Answer 1

Answer:

68°

→ 180° - ( 47° + 65° ) [ since, the sum of all the angles of a triangle are 180° ]

→180° - 112°

→68°

Answer 2

Answer:

one angle = 47°

2nd angle = 65°

sum of these two angles= 112°

sum of all the angles of a triangle is 180°

therefore the third angle=180-112=68°(ans).
