In the figure below, the length of CB is 64 units and the length of BG is 137 units. What is the length of EA?

first, determine the length of AG
RadEn
  • RadEn
AG = BG - BA

okay what would be BA?
anonymous
  • anonymous
I know that BG is 137
RadEn
  • RadEn
with BA = BC (because the triangle ABC is issoseles right triangle)
anonymous
  • anonymous
okay.....so......would I use a square root or something??
anonymous
  • anonymous
YES!! I do understand that part (:
RadEn
  • RadEn
opppss damn, typo AG = BG - BA AG = 137 - 64 = 73
anonymous
  • anonymous
okay I am following you!! lol :)
RadEn
  • RadEn
now, lets going to triangle of AGE
anonymous
  • anonymous
okay so after we figure out the AGE side then..we add 73??
RadEn
  • RadEn
remember that the property of right triangle 30-60-90, the proportion sides infront angles 30-60-90 is 1 : sqrt(3) : 2
anonymous
  • anonymous
yes I do remember learning about that so...then it would be 73 square root of three??
RadEn
  • RadEn
AG is side infront angle 30, while AE is side infront angle 90. so, just multiplied by 2 from side AG to get AE
RadEn
  • RadEn
AE = 2 * AG = 2 * 73 = 146
