Could I get some help with this please? I mostly just need an explanation on how to do it because I forgot, but if you want to give me the answer then that's okay too.
Thank you in advance! :)

A= 70 b=135 x=10

Step-by-step explanation:

A+110=180 because a straight line is always 180.

a triangle should equal 180 as well so you would put A+(5x-5)+(6x+5)=180. the +5 and -5 would cancel each other out. So you would be left with 70+5x+6x=180 (combine like terms) 70+11x+180 subtract 70 from both sides and will leave you with 11x=110 divid by 11 and x=10. plug 10 in for 5x-5. That will give you 45 and then 180-45=135.

520mg would be 0.520 gram
