Question

three angles of a quadrilateral are in ratio 3:5:2 and fourth angle is 160.find first angle​

Answer 1

Answer:

Let the angles 3x, 5x, 2x

3x +5x+2x+160 = 360 (angle sum property)

10x +160 = 360

10x = 200

x = 20 degree

so angles are:

60 degrees

100 degrees

40 degrees

160 degrees

Answer 2

Answer:

78

Step-by-step explanation:

take angles x

angles:3x,5x,2x

3x+5x+2x+160=360

10x+160+360

10x=260

x=26

first angle ratio=3x

then

3*26
