Step-by-step explanation:
x+8=10
x−4=22
x÷3=6
7x=28
60=30+30=6+6+6+6+6+6+6+6+6+6
a=a
a=b,thenb=a
60=30+30,then30+30=60
ifa=bandb=c,thena=c
60=30+30
30+30=6+6+6+6+6+6+6+6+6+6
60=6+6+6+6+6+6+6+6+6+6

Answer:
Step-by-step explanation:
We know a triangle adds up to 180 so:
75+36+ ? = 180
111+ ? =180
? = 69
To find out x, we know that a straight line adds up to 180 so again:
x +69 = 180
x = 111
BD is a angle bisector and Angle bisector theorem says
ratio of other sides of the triangle formed by bisector is equal
BA/AD=BC/CD
lets say AD is x so DC will be 4-x
3/x=4.5/4-x
x=1.6
AD=1.6units
so DC=4-x=4-1.6= 2.4 units
