Answer 1

Answer:

tanФ=5/12  now make an right angle triangle and mark Ф as any acute angle in it. write 5x as the side opposite Ф and 12x on the side adjacent to Ф (not the hypotenuse). the find hypotenuse by

√{(5x)²+(12x)²} = √{25x² + 144x²}=  √{169x²} = 13x

then, secФ= $\frac{13x}{12x}$= $\frac{13}{12}$

and, cosecФ=$\frac{13x}{5x}$=$\frac{13}{5}$

or, secФ+cosecФ= $\frac{13}{5} +\frac{13}{12} = \frac{221}{60}$ = 73.666666......≈73.666666667
