Answer:1 11/20 (I think)
Step-by-step explanation: First subtracting 3 - 2 gets you 1. so we keep that aside and do fractions. first, what do 4 and 5 have in common? They both can be turned to 20. 3/4 can be multiplied to 20 4x5(20) so we do 3x5=15 now you have 15/20. Hope this makes sense. now we do 1/5 to ?/20 5x4=20 1x4=4 so 15/20-4/20=11/20 11/20+1= 1 11/20
-Sorry if its too complicated
(undo ur answer if u trusted me before bc I messed up)
(its good now)
Answer:
9 cm
Step-by-step explanation:
The measure of ∠E will be equal to 38°.
Given,
m∠BFE = 118° and m∠C = 86°
And BF bisects ∠ABD
From the Property of Linear Pair,
∠AFB + ∠BFE = 180°
=> ∠AFB + 118° = 180°
=> ∠AFB = 62°
Now, we can see that ∠AFB and ∠FBD are equal because they are alternate angles.
And ∠FBD and ∠ABF are equal because BF bisects ∠ABD.
So, In ∆ABF,
∠AFB + ∠ABF + ∠BAF = 180° (because of the angle sum property of a triangle)
=>62° + 62° + ∠BAF = 180°
=>∠BAF = 180° - 124°
=> ∠BAF = 56°
Similarly, in ∆ABE,
∠A +∠C +∠E = 180°
=> 56° + 86° + ∠E = 180°
=> ∠E = 38°
Therefore, m∠E = 38°.
