Question

calculate the third angle of a triangle in which two of the angles are 47 degrees and 65 degrees

Answer 1

Answer:

sum of all interior angle of a Δ is 180

Let the third angle be x.

Therefore,

47+65+x=180

112+x=180

x=180-112

x=68

So, The third angle is 68 degree

Answer 2

Answer:

first angle =47

second angle=65

third angle=?

sum of all angles=180

47+65+x=180

112+x=180

180-112=x

68=x. this is answer
