Answer:
Step-by-step explanation:
Sine uses the ratio, so we can plug in the information we know. since there is no current value for the opposite side of angle A, we can just use a variable to replace it.
You can't reduce this any further because there is an unknown variable.
In triangle ABC and triangle CDA
AB=CD(given)
BC=DA(given)
AC=AC(common)
Thus triangle ABC and triangle CDA are congruent by SSS rule
x=62
y=45
