Will someone please do number 4 and 6 for me ?

1 answer:

8 0

4. all for angles need to equal 360
90 +90 + 42 = 222
360-222 = 138
y = 138 degrees
x - 42 degrees

6. x = arctan(8/4) = 63.43 degrees ( round as needed)
y = 16 / tan(63) = 8.15 ( round as needed)

633,248.
The difference of each 3 is that they have different place values.
The 3 on the right side is int he 1000s (thousands) place, and the 3 on the left is in the 10,000s (ten thousands) place. :)

The one in the 10,000s place is 10 times larger than the one in the 1,000s place!
