Answer:
Step-by-step explanation:
let the angles of a quadrilateral be 2x 3x 4x and 7x
2x+3x+4x+7x = 360 (sum of all angles of a quadrilateral)
16x = 360
x = 360/16 = 22.5
the angles of quadrilateral are
2x =2*22.5 = 45
3x = 3*22.5 = 67.5
4x = 4*22.5 = 90
7x = 7*22.5 = 157.5
it is a concave quadrilateral
Answer:
answer is 45°
Step-by-step explanation:
it is a convex polygon
