Answer:

216 cm^2

Step-by-step explanation:

A cube has 6 congruent, square faces.

Each face has side length of 6 cm.

The total surface area is the sum of the surface areas of the 6 faces, but since all faces are congruent, the total surface area is

SA = 6s^2

where s = side length

SA = 6 * (6 cm)^2

SA = 6 * 36 cm^2

SA = 216 cm^2

Using basic trigonometric identities simplify the

katrin2010 [14]

Answer:

Step-by-step explanation:

Using the trigonometric identities

cot x = $\frac{cosx}{sinx}$ and tan x = $\frac{sinx}{cosx}$ thus

$\frac{cos0}{cot0}$ + tanΘ × cosΘ

= $\frac{cos0}{\frac{cos0}{sin0} }$ + $\frac{sin0}{cos0}$ × cosΘ

= cosΘ × $\frac{sin0}{cos0}$ + sinΘ

= sinΘ + sinΘ

= 2sinΘ → b
