Answer:

1206 = 1000 + 200 + 0 + 6

1000 * 5 = 5000

200 * 5 = 1000

6 * 5 = 30

5000 + 1000 + 30 = 6030

So, 1206 * 5 = 6030

Sorry I took so long.

Hope this helps!

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....
