Angle ebc=3r+10 angle abe=2r-20 find angle ebf

Solution:

The angles EBC & ABE form a linear pair.

So, ∠EBC + ∠ABE= 180

3r+10+2r-20 = 180

5r-10=180

5r=180+10

5r=190

r=190/5

r=38

Substitude

Since, ∠EBF = ∠ABE

∠EBF = 2r-20

∠EBF = 2(38)-20

∠EBF=76-20

∠EBF=56 (Answer)

maximum area = xy = (16)(32) = 512 ft2

to maximize the area of the garden, the side of the fence parallel to the side of the house should be 32 ft long, and the other two sides should both have length 16 ft.'
