If the area is 168& the length is 2 feet more so length is 14& width is 12 (14*12= 168), the rug is 8feet in total less from all sides so it gives an area on 160. To come out with length& width knowing the length should be less than 14, so it could be either (10*16, 8*20)
Answer:
cos α = 8/17
Apply Pythagoras theorem for triangle ,
Let get unknown side of triangle is y
17^2 = 8^2 + y^2
17^2 - 8^2 = y^2
225 = y^2
y = sqrt(225)
y = 15
tan α = 15/8
