A coin and a pentagonal spinner with edges marked A, B, C, D and E are tossed and twirled simultaneously. Find the probability of getting A head and a D A tail and either an A or a D.

(Head and D) = 1/10

(Tails and A or D) = 1/5

Step-by-step explanation:

A coin has two sides so that a 50% chance that it will land on heads or tails

A pentagonal spinner has a 40% chance that it will land on D or A.

P (Heads) = 1/2

P (D)= 1/5

1/2 · 1/5 = 1/10

P (Heads and D) = 1/10

P (Tails) = 1/2

P(A or D) = 2/5

1/2 · 2/5 = 1/5

P (Tails and A or D) = 1/5

answer:  

step-by-step explanation:

here x represents the height of the pole,

and, the height of the shadow of the pole is 12 feet.

also, the angle of elevation from the top of the pole is 40°,

therefore,

by the low of sine,

which is the required equation for finding the value of x,

were is the equation
