Apply the properties of integer exponents to identify all of the expressions equivalent to

1/32

By the angle addition postulate, the size of angles RQS and TQS must sum to three angle TQR. S once angle TQR is a straight angle it measures 180°

6x+20+2x+4=180
8x+24=180
8x=156
x=39/2

angle TQS measures 6*(39/2)+20=137°
angle QSR measures 2*(39/2)=43°

if you add these you'll see they do sum to 180
