Question

Is it possible to have triangles with following sets of angles
1. 70, 40, 80 degrees
2. 45, 65, 70 degrees
3. 29,30,60,10,90,20
(Give reasons for ur answers)

Answer 1

Answer:

1) NO

2) YES

3) Not possible

Step-by-step explanation:

For case 1:- 70+40+80=180 [ASP of Δ.]

=> 210 is not equal to 180

For case 2:- 45+65+70=180 [ASP of Δ.]

=> 180=180

For case 3:- A Δ. have only 3 sides

Answer 2

Answer:

1) No

2)yes

Step-by-step explanation:

1) solution : 70+40+80=180

190=180

therefore it does not match

2) solution: 45+65+70=180

180=180

therefore it matches
