Answer:
1.If you are to check the figure you will find that it is a rectangles. You should know the properties of a rectangle.
- we are goin to use the property: Each vertex of a rectangle has angle equal to 90 degrees
- meaning since m∠SUT and m∠ RUS form the vertex when added they give 90°
3x+6+(5x-4)=90°
3x+5x+6°-4°=90°
8x+2°=90°
8x=90°-2°
8x=8°
2.m ∠SUT is donated by 3x+6
and now we know the value of x=11°
m∠SUT=3(11°)+6
m∠SUT=33°+6°
m∠SUT=39°
