What is the quotient of 90 ((cos(pi/4) + i sin (pi/4))/
2(cos(pi/12)+ i sin(pi/12))

45 (cos (15) + isi (1)
88(cos(1) + i sin (5)
45 (cos (Ts) + i sin (0)
88 (cos ( ) + i sin (1)

prime

the number 37 is prime

we can set up an equation to find the girls' ages. the equation is         28=0.5x-5+x. (comment if you need me to explain how i got this equation.) so, you add x and 0.5x to get 1.5x and add 5 to each side. your new equation is 33=1.5x. now divide both sides of the equation by 1.5 to get 22=x. because x is mary's age, to find jasmine's age we subtract mary's age from 28. we find that mary is 22 years old and jasmine is 6 years old.
