You should use your calculator for such simple sums. It is far quicker and involves fewer key depressions than posting the question on WA. I could tell you that the answer is 285 but how can you be sure that I did not make a mistake? Or that I am not messing about?

90+90+90=270 degrees your answer is 270 degrees
The LCM is 270.
18y+5y+48+15 = 270 18y+5y = 270-48-15 23y = 207 y = 9

15 and 270 do.
270
Since 270 is an even number, then three consecutive odd numbers cannot add to 270. ,because Odd + odd = even (2 numbers_ Even + odd = odd ( plus a third number) odd + odd = even (plus a fourth number) even + odd = odd (plus a fifth number) Notice from the table that the third odd number gives an odd answer; not an even answer. e.g. three odd numbers 3,5, & 7. 3 + 5 = 8 (even) 8 + 7 = 15 ( odd) et. seq.,
234/270 = 13/15
The LCM is 270.
18y+5y+48+15 = 270 18y+5y = 270-48-15 23y = 207 y = 9
