Find zw and z/w. Leave your answers in polar form. z = 9(cos 50*+ i sin50*)

w = 10(cos30*+ i sin30*)

What is the product?

zw = ? [cos ?* + i sin ?*]

z/w = ? [cos ?*+ i sin ?*]

(* = degree)

by definition, an arc subtended by a central angle of some given measure has the same measure. so .

30 miles

step-by-step explanation:

we know that 60 seconds equals 1 minute and 60 minutes 1 hour

44 ft       60 sec     60 min     158400   ft

  *   *   =

1 sec       1 min       1 hour         hour

we know that there are 5280 ft per mile

158400   ft       1 mile         30 miles

  *   =

1   hour               5280 ft     1 hour

so in 1 hour   it can travel 30 miles

m∠a is 90°

m∠b is 40°

ask the math teacher she or he would know lol.
