11!!!1 Can you solve an equation two different ways? Can you explain both methods?

Svetlana's hair is 4 4 centimeters ( cm cm) long. her hair grows 1 . 5 cm 1.5cm per month. svetlana wants her hair to be less than 1 6 cm 16cm long. write an inequality to determine the number of months, m m, svetlana can allow her hair to grow so that it is less than 1 6 cm 16cm long.

Can someone me with #s 8, 9, and 11. with just one of the three also works. prove using only trig identities.
