16.9 times 2.85
step-by-step explanation:
y = 5x + 17
a perpendicular line will be the opposite reciprocal slope of the given equation. the slope given is -1/5 so the opposite reciprocal is 5
find b:
7 = 5 (-2) + b
7 = -10 + b
17 = b
write equation
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)
wait nvm i know the correct answer now its 100% 81 square feet
