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

                                                  =2345

7 ft 6 in means 7 1/2, because 6 in is 1/2 of a foot. 7 ft 8 in means 7 2/3 because 8 in is 2/3 of a foot. 23/3 = 7 2/3. 15/2 = 7 1/2.

23/3   *   15/2   = 57 1/2
