Answer:
x=7
Step-by-step explanation:
UR & TS is parallel
so angle RTS is = to angle URT (29°)
and angle UTR is = to angle SRT (41°)
3 angles of a triangle = 180°
angle SRT = 41°
angle RTS = 29°
angle TSR = 15x+5
all three of those angles should add up to 180°
41+29+15x+5=180
15x+75=180
15x=105
x=7
