are in the ratio 3:4, then find all the interior angles of the triangle.​

Answer 1

Answer:

Step-by-step explanation:

105 degree

180 degree -105 degree

75 degree

3x +4x + 75 degree =180 degree

7x = 105 degree

so x =105/7

15 degree

15 * 3=45 degree

15*4  =60 degree

75 + 45+ 60 = 180 degree
