Question

sum of two angles of quadileteral of quadileteral is 180. The other two angle's are in the ratio of 2:7. find theses angles​

Answer 1

Answer:

The 3 angles ratio are 2:3:5

So 2X,3X,5X are the angles

2X+3X+5X =180 (As per the question)

10X=180

X=18 degrees

So 3 angles are

2*18=36

3*18=54

5*18=90

The 3 angles are 36,54,90 and the triangle is right-angled triangle.
