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

Answer:

3.24

Step-by-step explanation:

You would use the two fonts given to find the scale factor.

So the scale factor would be 10.4976/5.832 = 1.8

So if the scale factor is 1.8 we can use that to find the font size just before that. To do this you would divide the font size by the scale factor.

5.832/1.8 = 3.24

The font size just before 5832 is 3.24.
