Answer:
(d) 42°
Step-by-step explanation:
An angle bisector divides an angle into two equal parts. The original angle has double the measure of either of the parts.
__
setup
∠VSU = 2×∠VST
9x +3 = 2×(5x -3) . . . . . . . substitute given expressions
solution
9x +3 = 10x -6 . . . . . . eliminate parentheses
9 = x . . . . . . . add 6-9x
∠VST = 5(9) -3 = 42 . . . . degrees
__
m∠VST = 42°
