Answer:
i dont understand...the meaning?
Step-by-step explanation:
You just need to multiply 185 by 3. 185 x 3 = 555
I hope it's helpful for u but I am not sure my answer is right !
You times 4 by everything inside the parentheses, so the answer would be as follows. 16a + 20b - 12
I think it might be 43° because since the line is going through the middle, it would be 180-47-90=43 (the 90 came from the right angle)
hope this helps! :)
