Answer:
27
Step-by-step explanation:
let th original number=x
x+108=5x
5x-x=108
4x=108
x=108/4=27
Judging by the model I would assume that ΔDBC is congruent to ΔDBA.
Thus, line CD should be congruent to line AD as well, which the solution should be line CD=13 units.
Y-5=20
the y represents the unknown # that you used to subtract the five from
to find what y is you will need to ad 5 and 20 then y will be 25
5+20=25
25-5=20
y=25
It is a scalene triangle because all sides are different
The following expression is 23
