Question

Four angles of a quadrilateral 4:5:4:8 find their measure.​

Answer 1

Answer:

let the angles be 4x,5x,4x and 8x

Now,

4x+5x+4x+8x = 360° [sum of the all angles of a quadrilateral is equal to 360°]

21x = 360°

x = 360°/21

Now,

4x= 4×360/21= 68.571

5x= 5×360/21 = 85.714

4x= 4×360/21 =68.571

8x= 8×360/21=137.142

I think you haven't given the right ratios of the angles because the numeric values of angles can't be in decimal.

It means your question is totally wrong.
