whose two angles are 115° and20°plz tell the answer it's argent plz send pic of this ans plz​

Answer 1

Answer:

third angle=45°

Step-by-step explanation:

sum of all angles of a triangle=180°

Let the third angle be x

115°+20°+x=180°

135°+x=180°

x=180°-135°

x=45°

Answer 2

Answer:

Please mark me as Brainliest...

Step-by-step explanation:

We know that the sum of all the interior angles of a triangle is 180°....

So 2 angles are given...

so Take the 3rd one as x

So, x + 115 + 20= 180

x = 180- (115+20)

x = 180-135

x= 45°
