Answer:

Step-by-step explanation:

Sol'n

Let the remaining angle of a triangle be x.

x+71+56=180 (Sum of angles of a triangle is 180°)

or, x+127=180

or, x=180-127

.:, x=53°

.:, The measure of third angle is 53°

Volume of right trapezoid cylindar whole bases are B 16m, b 8m, height is 4m and length is 32m

viktelen [127]

Answer:

$volume = 1536 m^3$

Step-by-step explanation:

given data;

B = 16m

b =8 m

height H = 4 m

length L = 32 m

volume of any right cylinder = (Area of bottom) \times (length)

Volume = A* L

The area of a trapezoid is

$A=\frac{1}{2} H*(b+B)$

$A =\frac{1}{2} 4*(8+16)$

$A = 48 m^2$

therefore volume is given as

volume = 48*32

$volume = 1536 m^3$

Studio = 7 yards by 4 yards

Area = 7*4 = 28 square yards.

Area of square carpet = 1 yard * 1 yard = 1 square yard

Number needed = Area of studio / Area of square carpet = 28 / 1 = 28

Number needed = 28
