2x + 2(5+x)=10
2x+10+2x=10
4x+10=10
4x=0
X=0
First you do 16.06 divid by 22 which equals 0.73 cents
BD is 31 degrees because it is the same.
ADB is 90-31 because it is a right angle ( 59 degrees)
DEC is 180 - (31*2) because the 180 is of the trangle and the 31 is the same on the other side so times 2 then removed from 180
I honestly do not know this seems to me to be a trick question
