PLZ ANSWER PLZ PLZ PLZ HELP 1 QUESTION!!!
JulsSmile [24]

We first must find the value of angle z.


Angle z = 90° - 42°


Angle z = 48°


We now use the sine function to find y.


sin(48°) = 35/y


y = 35/sin(48°)


y = 47.0971455362


We now round off to two decimal places.


y = 47.10


I hope this helps....
