The spinner is equally likely to land on any of the five sections.

what is the probability that the spinner lands on an even number or on the unshaded section?

a- 1/5
b-2/5
c-3/5
d-4/5

we know that

the probability of an event is the ratio of the size of the event space to the size of the sample space.

the size of the sample space is the total number of possible outcomes

the event space is the number of outcomes in the event you are interested in.

so

p=size of the event space/size of the sample space

step

find the probability that the spinner lands on an even number

size of the sample size=

size of the event space=

step

find the probability that the spinner lands on the unshaded section

size of the sample size=

size of the event space=

step

find the probability that the spinner lands on an even number or on the unshaded section

sum the probability find in step and the probability find in step

therefore

the answer is

the probability is equal to

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth

step-by-step explanation:

c. 27 units.

step-by-step explanation:

we are told that in circle a, ∠bae ≅ ∠dae.

we can see from our given diagram that in and ;

, as these are radii of our given circle.

therefore, by sas congruence postulate.

hence, side be will be equal to side de as corresponding parts of congruent triangles are congruent. so we can set an equation to find the value of x as:

now let us substitute x=17 in the expression for the length of be.

therefore, length of be will be 27 units and option c is the correct choice.
