Math will givebrainliest and 20 ! 1.what is the area of a regular hexagon with a side length of 12 cm? enter your answer in the box. round only your final answer to the nearest hundredth. 2.in a 30-60-90 triangle, what is the length of the hypotenuse when the shorter leg is 5 cm? 3. what is the exact value of sin 30° ? enter your answer, as a simplified fraction, in the box.

 Question 1:
 
 By definition, the area of a regular hexagon, depending on its sides, is given by:
 
 Where,
 L: side of the regular hexagon.
 Substituting values we have:
 
 
 Rounding to the nearest hundredth we have:
  
 The area of a regular hexagon with a side length of 12 cm is:
 

 Question 2:

 By definition, sides of a triangle 30-60-90 are given by:
 Largest side:
 Smallest side: x
 hypotenuse: 2x
 Therefore, since the smallest side length measures 5 cm, then the hypotenuse is:
 
 
 the length of the hypotenuse when the shorter leg is 5 cm is:
 10 cm

 Question 3:

 The first thing you should know for this case, is that angle 30, is a notable angle.
 Therefore, the values of the sine are defined for notables angles.
 The notable angles are:
 0, 30, 45, 60, 90
 Therefore, the value of sine (30) is given by:
 sine (30) = 1/2
 
 the exact value of sin 30 ° is:
 sine (30) = 1/2

Iam not good at math i wish i could
