solve this with explanation.....

Answer 1

Step-by-step explanation:

Now there are 10 angles which qualifies a decagon.

so the total angle = 1440°

since it's an identical kite as shown in the fig, 5 acute angles will be of same measure and the other 5 reflex angles will be the same

which means,

5x+(5×40)= 1440° (measurement of acute given in fig)

5x= 1440-200

x= 1240/5= 248°

so the five other reflex angles are 248°each

now since ∅ is opposite angle of one of reflex angles

we have

248+∅= 360

∅= 360-248

= 112°
