Step-by-step explanation:

the formula is :

tan (a+b) =

(tan (a) + tan (b)) / ( 1 - tan (a) . tan (b))

therefore

tan (π/5) + tan (π/2)) / (1-tan (π/5) tan (π/2))

= tan (π/5 + π/2)

Helena lost her marbles. But then she found them and put them in 444 bags with mmm marbles in each bag. She had 333 marbles left

galben [10]

Answer:

y = 444mmm + 333

Step-by-step explanation:

let total marbles = y

putting mmm marbles in 444 bags we have the total in the bags to be 444mmm

but there are 333 marbles left that didnt fit in the bags giving us (+333)

adding them both together

therefore the total marbles will be 444mmm + 333
