Question 1108294: triangle CDE sits atop square ABCD, CE is perpendicular to CD, and CED=2 x mCDE what is the measures of CED and CDE Answer by rothauserc(4718) (Show Source):
You can put this solution on YOUR website! triangle CDE is a right triangle with m ECD = 90 degrees
:
m CED + m CDE = 180 - 90 = 90 degrees
:
m CED = 2 x m CDE
:
let z = m CDE, then M CED = 2z
:
z + 2z = 90
:
3z = 90
:
z = 30
:
*****************************************
m CED = 2 x 30 = 60 degrees
m CDE = 30 degrees
