Question

the four angles of a quadrilateral are in the ratio 3:4:5:6 . the measure of its smallest angle is options are i 120 ii 36 iii 18 iv 30 please tell fast and right​

Answer 1

Ok,
We know that the sum of all interior angles in a quadrilateral are 360 degrees.
Let’s take the constant magnitude as x:
So, 3x + 4x+ 5x + 6x = 360 degrees.
18x = 360 degrees.
x = 20 degrees.
Smallest angle = 3(20) = 60 degrees.
