Question

angles of a quadrilateral are in a ratio 7:6:2. the sum of these angles is 300. the smallest angle of the quadrilateral is ________ cm.

Answer 1

7x + 6x + 2x = 300
=> 15x = 300
=>x = 300/15
=> x = 20

now, the smallest angle is in the ratio '2'

2x is the smallest angle

2x = 2(20)= 40

therefore , the smallest angle of the quadrilateral is 40cm

Answer 2

Answer:

32 degrees

Step-by-step explanation:

let the angles be 2x , 6x , 7x as given in question

then 2x+6x+7x+y = 300

y is equal to 60 degree as sum of angles of quadrilateral is 360

15x = 300-60

x = 240/15

x = 16

smallest angle will be 2x = 32
