okay, from the figure we know that angle ABD= 3x = 90 Can you find value of x?

Do I just divide 90/3? Sorry for all the stupid questions
ash2326
  • ash2326
ok, let me explain we have 3x= 90 divide both sides by 3 3x/3= 90/3 or x= 90/3 Do you follow? No question is stupid :)

ooohh, so how do I solve for Y?
ash2326
  • ash2326
what is the value of x you got?
anonymous
  • anonymous
x=30

  • ash2326
good, what's the value of angle ABC?
anonymous
  • anonymous
ABC is 180 degrees
ash2326
  • ash2326
good, so what's angle DBC?
anonymous
  • anonymous
DBC is 90
ash2326
  • ash2326
good, also from figure angle DBC= 2x+3y =90 so we have 2x+3y=90 Can you solve for y? you already know the value of x?
