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)

I’m not entirely sure how to answer this without a word problem, but from what I see, all you have to do is multiply the two numbers.
12 x 43= 516
5 x 88 = 440
8x 63= 504
7 x 28= 196
Usually, when you see a number followed by another number in parentheses, like here, that means to multiply.
