Let's begin by sketching the triangle with its angle bisectors.
Considering the Triangle-Angle-Bisector Theorem, let's find the lengths of each pair of segments one at a time.
We will first consider BD and DC.
As our second pair of segments, we will think of AE and EC.
Substitute values
Cross multiply
Distribute 5
LHS+5AE=RHS+5AE
.LHS /18.=.RHS /18.
a/b=.a /6./.b /6.
Rearrange equation
Calculate quotient
Round to 1 decimal place(s)
Finally, we will find AF and FB.
Substitute values
Cross multiply
Distribute 12
LHS+12AF=RHS+12AF
.LHS /5.=.RHS /5.
a/b=.a /5./.b /5.
