2x + 24 + y+ z + w = 360 solve for x y z w
you can solve it using matrix method.
to solve for x, move all other numbers and variables to the other side. so subtract 24 y z and w from 360 to get 2x=336-y-z-w then to finish solving for x, divide by 2. you can use a similar method to find the individual values of y, w and z
its for the interior angles of a trapezoid i need to label the measures
oh, then that is quite different. can you supply a picture?
no but 2x + 24 is the top right angle bottom right is just x and the whole left side is blank i know that togethor the angles equal 360
well the base angles of an isoceles trap are congruent, so you can start there. also, opposite angles of a quadrilateral are supplementary, so that should also help you get started :)

sorry, okay here we go: 2x+24+x=180 because they are consecutive interior angles (recall that the top and bottom of trapezoids are parallel). solve this, what do you get for x?
no, you should first combine like terms and you should have 3x=180-24. can you solve it now?
52
*x=52
correct. so x is 52, mening the bottom right angle is 52 and the top right angle is 52+24
*correction, the top right angle is 52*2+24
what is the bottom right then
te bottom right is 52, because x=52
the top right is 128
correct
how do i do the left side it has to equal 180 right
or does it not matter because it is not labeled
thank you
no problem :) hope this helped... geometry can be hard, but if you get down those theorems you will be amazed how much everything makes sense :)
