Nnesha (nnesha):

there is right triangle so triangle equal to what ???

OpenStudy (anonymous):

180

Nnesha (nnesha):

|dw:1414955943086:dw| this measure of this angle is what

OpenStudy (anonymous):

90

Nnesha (nnesha):

so 90 -38 = ???

OpenStudy (anonymous):

52

OpenStudy (anonymous):

128

OpenStudy (anonymous):

256

Nnesha (nnesha):

wait is that <xyz or <xwy

OpenStudy (anonymous):

OpenStudy (sleepyjess):

The angles XYZ and XYW form 180 degrees added together so first we need to find XYW.

OpenStudy (sleepyjess):

Given that YWX=38 and WXY=90 we can figure out the measure of XYW knowing that a triangle has 180 degrees.

OpenStudy (anonymous):

<x +<w + <y = 180 90 + 38 + y = 180 128 + y = 180 y = 180 - 128 = 52 degree <y = xyw xyw + xyz = 180 straight lne 52 + xyz = 180 xyz = 180 - 52 = 128

OpenStudy (sleepyjess):

180-90-38=52 Since XYZ and WXY must add up to 180 now do 180-52 to find the measure of XYZ. 180-52=128
