[Right Triangles Only] SOHCAHTOA
[Right Triangles Only] cosθ = adjacent over hypotenuse

Step-by-step explanation:

Step 1: Define

Angle θ = 28°

Adjacent Leg = EF = x

Hypotenuse = DF = 18

Step 2: Solve for x

Substitute in variables [Cosine]: $\displaystyle cos28^\circ = \frac{x}{18}$
[Multiplication Property of Equality] Multiply 18 on both sides: $\displaystyle 18cos28^\circ = x$
Evaluate trig: $\displaystyle 18(0.882948) = x$
Multiply: $\displaystyle 15.8931 = x$
Rewrite: $\displaystyle EF = 15.8931$
Round: $\displaystyle EF \approx 15.9$

Asher has about a probability of winning then Ethan has which could be the outcome that Ashlee needs to win the game select thre

mash [69]

Answer:

There are 36 total possible outcomes.

Rolling a sum of 11 or higher, there are 3 possible rolls, to make a 3/36 = 1/12 probability.

Rolling a sum of 4 there are also 3 possibilities, so the chance would be the same.

Rolling a sum of 9, there are 4 possibilities, which is a better chance.

Rolling a sum less than 5, there is 6 possibilities, which is a better chance.

Rolling greater than 5 but less than 7 means rolling a sum of 6, there are 5 chances, which is a better chance.

Rolling greater than 9 but less than 11, means rolling a 10, there are 3 possibilities, which is the same.

Rolling greater than 2 and less than 4 means rolling a 3, there are 2 possibilities, which is less.

The answers would be:

Rolling a sum of 9,

Rolling a sum less than 5

Rolling greater than 5 but less than 7
