Question

3. Three angles of a quadrilateral are in the ratio 2 : 5:6. If the fourth angle measures 100°, find
the other three angles of the quadrilateral.​

Answer 1

Answer:

Step-by-step explanation:

Let all three angles be 2x,5x and6x

The fourth angle = 100°

Now

2x+5x+6x+100° = 360° ( quadrilateral sum 360°)

13x = 360°-100° = 260°

x = 260/13 = 13

Now,

2x = 2×13 = 26°

5x = 5×13 = 65°

6x = 6×13 = 78°
