Rewriting the left hand side,

= 1/sin²t - 1

= 1/sin²t - sin²t/sin²t

We have that 
the volume of a right square pyramid ---------- > (1/3)b²h

Let
V1------------ > initial volume
V1=(1/3)b²h

<span>if its height is multiplied by 8
</span>
V2=(1/3)b²(8h)-------------- > V2=V1*8

Step-by-step explanation:

a = age of Alex

l = age of Lucy

m = age of Megan

a + l + m = 126

l = 3a

l = m + 7

=>

a = l/3

m = l - 7

we are using that in the first equation :

l/3 + l + l - 7 = 126

l + 3l + 3l - 21 = 378

7l = 357

l = 357/7 = 51

a = l/3 = 51/3 = 17

m = l - 7 = 51 - 7 = 44

the ratio of the age of Lucy to Alex to Megan is

51 : 17 : 44
