Cos Z = 32/40 => Z= cos-¹(32/40) =>
sin Z = sin (cos-¹(32/40)) = 3/5

Plug in what we know:

Find the cube root of both sides:
![\sf~a=\sqrt[3]{2744}](https://tex.z-dn.net/?f=%5Csf~a%3D%5Csqrt%5B3%5D%7B2744%7D)
Simplify:
First find out how many Carly sold:-
90 ÷ 2 = 45
Carly sold 45 rolls
Add to find out how many the sold together:-
90 + 45 = 135
Jasmine and Carly sold 135 rolls of wrapping paper together.
.6578 this would be the answer
