@Lully1212 what two angles can you add that will equal JKL?

@billj5 you can add HKL and JKH together but that would equal up to 178
anonymous
  • anonymous
that is correct, so please set up the equation
anonymous
  • anonymous
value of HKL + value of JKH = 172, plug in the values
anonymous
  • anonymous
153x + 25x = 172
anonymous
  • anonymous
not quite
anonymous
  • anonymous
(153 + x) + (25 + x) = 172 153 + x + 25 + x = 172
anonymous
  • anonymous
does that make sense?
anonymous
  • anonymous
So far it does
anonymous
  • anonymous
ok great please simplify this 153 + x + 25 + x = 172
anonymous
  • anonymous
153 + x + 25 + x = 172 - 25 - 25 128 i dont think i did that right lol
anonymous
  • anonymous
just combine like terms, lets rearrange first, 153 + 25 + x + x = 172
anonymous
  • anonymous
153 + 25 = what?
anonymous
  • anonymous
172
anonymous
  • anonymous
178 + x + x = 172
anonymous
  • anonymous
x + x = what?
anonymous
  • anonymous
2x
anonymous
  • anonymous
perfect so we have 178 + 2x = 172, does this make sense?
anonymous
  • anonymous
we were just combining like terms on the left hand side
anonymous
  • anonymous
Yes
anonymous
  • anonymous
ok perfect, can you solve this equation 178 + 2x = 172?
anonymous
  • anonymous
Do i just subtract 172 from 178?
anonymous
  • anonymous
you can, the first goal is to get the x terms by themselves on one side of the equation, so i would probably subtract 178 from 172
anonymous
  • anonymous
So that would equal -6
anonymous
  • anonymous
correct, so we have 2x = -6
anonymous
  • anonymous
so what is x equal to?
anonymous
  • anonymous
x = -3?
anonymous
  • anonymous
perfect, good work :)
anonymous
  • anonymous
Thank you :)
