m < C + m < D = 180 x + 39 = 180 solve for x

ironic how angle C matches with choice C, but yeah it's correct

Based on the information given, can you determine that the quadrilateral must be a parallelogram? Explain. Given: XY congruent to WZ and XW congruent to YZ (1 point) Yes; opposite sides are congruent. Yes; diagonals of a parallelogram bisect each other. Yes; two opposite sides are both parallel and congruent. No; you cannot determine that the quadrilateral is a parallelogram.

XY = WZ (given) XW = YZ (given) opposite sides are congruent, so we definitely have a parellelogram

can you help me with this? mR = 130 and mS = 80. Find mT. The diagram is not to scale. (1 point) 65 70 35 80

jim_thompson5910 Group TitleBest ResponseYou've already chosen the best response.0
no it wouldn't be c because we can't determine the two opposite sides are parallel (yet)

jim_thompson5910 Group TitleBest ResponseYou've already chosen the best response.0
the only thing we are given is that the opposite sides are congruent

then fill in what you know dw:1358923381801:dw Note: segment RT is a angle bisector of angle SRU, so angle SRT is half of angle SRU (130/2 = 65)

solve for x, then double the value of x to get the angle T

Emily778 Group TitleBest ResponseYou've already chosen the best response.1
how do I solve for x for this?
 one year ago

jim_thompson5910 Group TitleBest ResponseYou've already chosen the best response.0
if you're not sure how to get x, add up all the angles and they should result in 180 degrees so x+65+80 = 180

jim_thompson5910 Group TitleBest ResponseYou've already chosen the best response.0
close, but you have to double it
