Answer 2

Answer:

angle y = angle TRQ= 90(alternative angle)

angleQRS = angle RQP

angle y+angle PQU=angle X +angleTRQ

90+angle PQU=angle X+90( 90 and 90 get cancel)

angle PQU=angle X

angle PQU=180-150(supplementary angles)

angle PQU=30=angle X

given that:8x-2y

= 8(30)-2(90)

= 240-180

= 60
