Question

the angle of a quadrilateral are 4x) (7x) are (15x) and (10x) find the smallest and largest angles of the quadrilateral

Answer 1

u can find it by using angle sum property of a quadrilateral.
4x+7x+15x+10x = 360
36x = 360
x = 10
smallest angle= 4 *10=40
largest angle = 15*10=150

Answer 2

Here is your answer

Hope it helps you

Sum of all angles = 360°
4x + 7x + 15x + 10x = 360
36x = 360
x = 10°

So smallest angle = 4x = 40°
Largest angle = 15x = 150°
