Question

the angles of a quadrilateral are in the ratio 2:3:7 the mean of these angles is 64 degree find all the four angles​

Answer 1

Answer:

Step-by-step explanation:

(let us name the quadrilatral as pqrs)

sum of all angles of a quadrilateral is 360 degree.

sum of the angle is 12(2+3+7=12)

so.2+3+7=360.

    angle p=2/12*360=60

    angle q=3/12*360=9

    angle r=7/12*360=21.
