Use proportional reasoning to determine the value of a in the proportion shown below. Q+5 unlu O a = 1
O q = 25
O a = 10
O a = 15

δabc ≅ δdcb by sas because

db ≅ ac . . given (side)

bc ≅ bc . . reflexive property (side)

∠dbc ≅ ∠ acb . . alternate interior angles where transversal bc crosses parallel lines bd and ac (included angle)

what is the question? i am guessing you are looking for the area.

to find an area, you have to do length x width.

in this case, it would be 12 ft x 4 ft = 48 sq. ft

d. 145*2 is 290 than the total angle is 360 then minus 290 then divide by two
