Correct answer is: distance from D to AB is 6cm
Solution:-
Let us assume E is the altitude drawn from D to AB.
Given that m∠ACB=120° and ABC is isosceles which means
m∠ABC=m∠BAC = 
And AC= BC
Let AC=BC=x
Then from ΔACD , cos(∠ACD) = 
Since DCB is a straight line m∠ACD+m∠ACB =180
m∠ACD = 180-m∠ACB = 60
Hence 
Now let us consider ΔBDE, sin(∠DBE) =

Answer:
r=-2.5
Step-by-step explanation:
collect like terms
0.25r+0.5r
0.75r-0.125=0.5+r
move terms
0.75r-r=0.5+0.125
collect the like terms
-0.25r=0.625
divide both sides by -0.25 to get your answer.
