Answer:
The length of BC is 17.
Step-by-step explanation:
From the given figure ∠ B = ∠C
It means that AB = AC
i.e. 2 x - 8 = x + 9
2 x - x = 8 + 9
x = 17

Answer:
9 rolls
Step-by-step explanation:
The perimeter of the room measures 2(19' +12') = 62', so the area of the walls is ...
(62 ft)(8.5 ft) = 527 ft²
We know that 8 rolls will cover 8×60 ft² = 480 ft², and 9 rolls will cover 540 ft², so we will need 9 rolls to cover the walls.
area = pi * r^2
here, the radius is 2 as its the diameter/2.
so the area is 4pi.
circumference = 2*pi*r.
so the circumference is 4pi as well.
