Answer:
Domain:(−∞,∞),{x|x∈R}
Range:(−∞,∞),{y|y∈R}
Step-by-step explanation:
Answer:
Step-by-step explanation:
Height of wall = 10ft
Length of ladder = 12ft
Angle of elevation be x
Sin x = opp/hyp
Sin x = wall height/length of ladder
Sin x = 10/12
Sin x = 0.83
X = Sin-¹ (0.83)
X = 56.44°
the are of parallelogram is A=bh
