Question

find the complementary angles of the following angles 30degree 45'​

Answer 1

Step-by-step explanation:

180-30=150

therefore it is the complementary angle of 30

180-45=135

therefore it is the complementary angle of 45

Answer 2

Answer:

Basically COMPLEMENTARY ANGLES are those angles who when summed up gives you 90(degrees) in total.

So as per your question,

                 In 1 min or 1' =1/60 (degrees) , which in approximation=0.0166667

Step-by-step explanation:

    So in 30 degree 45 min we have 45'=45/60 (degrees)

                                    =>>   30+0.75=30.75(degree)

so, Now  

                     let complementary angle be x and another is already given so,according to definition,

                           =>>     x+30.75=90

                            =>> x=90-30.75

                          =>>   x=59.25 (degrees) (approx.)

So complement of 30 degrees 45' is 59.25 (degrees)
