Determine the perimeter of the following triangle, to the nearest whole unit.

2345

Step-by-step explanation:

 The perimeter is the sum of all sides of the triangle.

  Let us find the sides of the given triangle;

Using sine rule:

                          =  =

To find angle A;

   90 + B + A = 180

    90 + 27 + A = 180

                    A = 180 - 117  = 63°

A =  63°

B = 27°

             =

A = 63°

 a = ?

C = 90°

c = 1000

                =

                 a = 1000Sin63  = 891

               =

B = 27

               =

                b  = 1000Sin27 = 454

The perimeter of the triangle  = a + b + 1000

                                                 = 891 + 454 + 1000

step-by-step explanation:

sin(7pi/6 - pi/3)  

= sin(7pi/6 - 2pi/6)  

= sin(5pi/6)  

= sin(pi - pi/6)  

= sin(pi/6)  

= 1/2  

sin 7pi/6 - sin pi/3  

= sin (pi + pi/6) - sin pi/3  

= -sin pi/6 - sin pi/3  

= -1/2 - sqrt(3)/2  

= -(1+sqrt(3))2
