Need help with some inverse trigonometric expressions, rounded to the nearest degree.
rjkz [21]
A Google or Bing search box can be your friend, if you don't have a calculator with inverse trig functions. Most calculators that have trig functions also have the inverse functions, usually after a 2nd or "shift" key. Often, there is a mode setting for degrees or radians.

arcsin(0.33) ≈ 19°
arccos(0.47) ≈ 62°
arctan(1.21) ≈ 50°
arcsin(0.82) ≈ 55°

Margarita [4]

Answer: The length of pencil is 16 centimetres and length of crayons is 8 centimetres

Step-by-step explanation:

Let the length of crayon =x

Length of a pencil =2x

As according to question that the sum of their length is 24 centimetres

So we have

x+2x=24\\\\\Rightarrow 3x= 24 \\\\\Rightarrow x= \dfrac{24}{3} =8

Therefore the length of crayon = 8 centimetres

Length of pencil= 2x= 2\times x = 2\times 8 =16 centimetres

Hence, the length of pencil is 16 centimetres and length of crayons is 8 centimetres
