Answer:
Angle XYV= 120 degrees
Step-by-step explanation:
Remember that interior angles in a quadrilateral= 360 degrees and angles on a straight line= 180 degrees
angleWXY + angleYXV =180 degrees (angles on a straight line)
hence, 3x + x= 4x, 4x=180
x=45
angleYXZ + angleXYV + angleYVZ + angleVZX = 360 degrees(angle sum of quadrilateral)
hence, x+ angleXYV + 3x + 60 = 360
4x + angleXYV = 360
sub x= 45
angleXYV = 360-4(45)
=120

The answer is the third one need any more help let me know
Answer:
( f o f )(x) = f ( f (x))
= f (2x + 3)
= 2( ) + 3 ... setting up to insert the input
= 2(2x + 3) + 3
= 4x + 6 + 3
= 4x + 9Step-by-step
