$1.80 if the question was ( he would have 3/5 of the amount he started with)
Answer:
Step-by-step explanation:
∠CFE is made up of ∠3 + ∠4; therefore,
∠3 + ∠4 = 74
∠BFD is made up of ∠2 + ∠3; therefore,
∠2 + ∠3 = 103
∠BFE is made up of ∠2 + ∠3 + ∠4; therefore,
∠2 + ∠3 + ∠4 = 136
and we are looking for the measure of ∠CFD which is ∠3.
Begin by using the fact that ∠3 + ∠4 = 74 and sub that into ∠BFE:
∠BFE = 136 and
∠2 + (∠3 + ∠4) = 136 and
∠2 + 74 = 136 so
∠2 = 62
Now use that in ∠BFD since
∠BFD = 103 and
∠2 + ∠3 = 103 and
62 + ∠3 = 103 so
∠3 = 41
