The answer is 8 1/2! Hope this helped :)
∠ABC=∠CDA=72º
∠DAB=∠BCD=x
∠ABC+∠CDA+∠DAB+∠BCD=360º
Therefore:
72º+72º+x+x=360º
144º+2x=360º
2x=360º-144º
2x=216º
x=216º/2
x=108º
So, <span>∠DAB=∠BCD=x=108º
Answer: </span>∠DAB=108º (B)

Step-by-step explanation:
There is a 6/30 chance that Cara got a date that was a multiple of 5 since there are 6 multiples of 5 in a matter of the 30 days of June (5, 10, 15, 20, 25, 30). There is also a 3/8 chance that she will chose a vowel in the word MATHLETE since there are 3 vowels within these 8 letters (A, E, E). With this information, you must multiply the fractions of 6/30 and 3/8 together in order to find the probability of chosing both a multile of 5 as well as a vowel. This can be done by multiplying the numerators together and the denonimators together and then simplifying the fraction to receive an answer of 3/40.
