Since the side is a transversal to the parallel bases, the angles formed are supplementary. This lets you write the relation
... (3x-5)° + (5x+13)° = 180°
... 8x +8 = 180
... x = (180 -8)/8 = 21.5
The value of x is 21.5.
Answer:
y=4x-2
Step-by-step explanation:
Every square is always rectangle because it is a quadrilateral with all four angles, right angles
3x+6y+5y-2y
Combine like terms
3x+9y
Answer=3x+9y
