The value of sin (180+x) is equivalent to
a)-sinx
b)-sin (90-x)
c)sinx
d)sin (90-x)

if sec (a+15) =csc (2a) find the smallest positive value of a in degrees.

and q38

3 is greater then both of those numbers

step-by-step explanation:

because 1/3 is a fraction. we can tell because there is a divisor symbol between the 1 and the 3. if we were to add 2 fractions together, we would add the numerators, which is the number on top, but not the denominators, which is the number on the bottom

1/3+1/3=2/3

hope this !
