Answer:

tana + tanb

Step-by-step explanation:

Using the trigonometric identities

• sin(a + b) = sinacosb + cosasinb

• tanx = \frac{sinx}{cosx}, then

\frac{sin(a+b)}{cosacosb}

= \frac{sinacosb+cosasinb}{cosacosb}

= \frac{sinacosb}{cosacosb} + \frac{cosasinb}{cosacosb}

= \frac{sina}{cosa} + \frac{sinb}{cosb}

= tana + tanb

30 treadmills to 36 elliptical machines the ratio in simplest form
Goshia [24]
30 treadmills : 36 ellipticals
this could be written in a few ways, but i am going to write it as a fraction. since treadmills come first, you put 30/36.

now that you have your fraction you have to find the GCF (greatest common factor) of the two numbers. the GCF is 6, so you have to divide 30 treadmills by 6, and 36 ellipticals by 6.
30/6=5
36/6=6

5/6 or 5:6 is the simplified ratio of treadmills to ellipticals
