Question

Three angles of a quadrilateral are in the ratio
1:2:3. The mean of these angles is 32°. Find all the
four angles.
​

Answer 1

Step-by-step explanation:

Let the angles be x, 2x, 3x then :-

(x + 2x + 3x )/3 = 2x = 32

x= 16°

So the angles are 16°, 32°, 48° & 84°

Answer 2

Answer:

angle A= 1x

angle B = 2x

angle C = 3x

mean = 32 = (1x + 2x + 3x)/3

2x= 32

x= 16

angle A = 16

angle B = 32

angle C= 48

angle D = 360 - (16+32+48)

= 360- 96

= 264
