The spinner is divided into equal parts. use a tree diagram to find the probability that the spinner will land on a vowel both times, if the spinner is spun twice. a. b. c. d.

Answer is

Step-by-step explanation:

Given is a spinner which is divided into equal parts of three.

One part has E, next part has U and third part has N.

Vowels are E, U comprising 2/3 of the area of the circle.

Tree diagram would be

I spin .... prob 2/3 ...landing on vowel .... ii spin ... prob 2/3 ... landing on a vowel

Hence required probability = product of two probabilities

=

  21.3

step-by-step explanation:

multiplying the given equation by c/sin(25°), we get

  c = 9/sin(25°) ≈ 21.2958 ≈ 21.3

we assume "c" is the length of ab, the side opposite angle c in triangle abc.
