Since the angle to the right of the angle are vertical angles with 41 it is safe to assume that the one next to it is also 41. So you add 56+41 and then set it equal to 180. 56+41+X =180 So you get 97+X=180 and then you subtract 180-97=X so X =83. And you can double check this by plugging it in to the equation.

97+X(83)=180

Simply 9+3(8-3(7-5))-4
EastWind [94]

Answer:

11

Step-by-step explanation:

  1. 9+3(8-3(7-5))-4
  2. 9+3(8-3(2))-4
  3. 9+3(8-6)-4
  4. 9+3(2)-4
  5. 9+6-4
  6. 15-4
  7. 11

I first delt with simplifying the parentheses till step five. Then in five I just added 9+6 because it came before the -4. But PEMDAS is very important when doing these problems because it tell you the order

  • P (parentheses)
  • E (exponents)
  • M (multiply)
  • D (divide)
  • A (add)
  • S (subtract)
  • **the biggest thing is that with multipe and divide it depends what comes first. If you see divide before multipe in the problem just do it that way. It is the same way with add and subtract but The multiple/divide group ALWAYS comes BEFORE add/subtract
