Os 105° and the interior Deste Opposite
angles are in the ratio 2:5. Find the
angles of the traingle-


solve this problem who slove this problem I will mark as brainlist​

Answer 1

Answer:

Let the opp. angles=2x & 5x

Ext. angle=105⁰

Explanation:

Sum of 2 opp. int. angles=Ext. angle

2x+5x=105⁰

7x=105⁰

x=15⁰

So, 1st angle=2x=2(15)=30⁰

2nd angle=5x=5(15)=75⁰

3rd angle=180⁰-(30+75)=75⁰    (As sum of all 3 angles of a triangle=180⁰)
