1.	Four angles of a quadrilateral 4:5:4:8 find their measure.
Answer» 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. But by this format you can SOLVE similar questions EASILY but if your question is correct.

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.
