Answer: 19
Explanation:
From the properties of the kite, we know that line segment XY is congruent to line segment ZY. Keep in mind, the variable we need to solve for this question is x!
From this, we can say that;
3x+4=5x-6
Plus 6 on both sides to get
3x+10=5x
Minus 3x on both sides to get
10=2x
divide both sides by 2 to get
5=x
now plug the x value 5, into the equation XY
3 times 5 + 4
multiplication goes first!
15+4=19
