What Is The Value Of Y?

Answers

Answer 1

9514 1404 393

Answer:

  y = 8√3

Step-by-step explanation:

In the 30°-60°-90° "special" triangle, the ratio of sides lengths is ...

  1 : √3 : 2 = 8 : y : hypotenuse

In order for these ratios to be equal, we must have ...

  y = 8√3

__

If you want to solve this using your trig skills, you recognize that ...

  Tan = Opposite/Adjacent

  tan(30°) = 8/y

  y = 8/tan(30°) . . . . where tan(30°) = 1/√3

  y = 8√3

Answer:

Area = 240 cm²

Step-by-step explanation:

Area of the shape = area of rectangle + area of triangle

= L*W + ½*bh

L = 18 m

W = 10 m

b = 10 m

h = 30 - 18 = 12 m

Plug in the values

Area of the shape = 18*10 + ½*10*12

= 180 + 60

= 240 cm²

Answers

Answer:

<GHI = 135 degrees

Step-by-step explanation:

(3x + 12) + (x + 4) = 180

4x + 16 = 180

4x + 16 - 16 = 4x

180 - 16 = 164

4x = 164

4x / 4 = x

164 / 4 = 41

x = 41

3 * 41 + 12

3 * 41 = 123

123 + 12 = 135

Answers

Answer:

The answer is 69.5

Step-by-step explanation:

First u wanna find the area of the rectangle and since it already gives you the the height and width you want to multiply them together 13×4= 52

meanwhile triangle is 5ft tall and the base is 7ft

using the formula to solve for area of a triangle you would multiply height and base and divide by 2

you should end up with 17.5 then u add that to 52 and get 69.5 ♡ Hope this helps.

Tarzan is making his mom a card for her birthday. He drew a model of the card before he created it. The model is shown below.

b = 9

A = 12 * 9 / 2

A = 54 inches

54 / 3 = 18

He needs 18 feet of paper

Answers

Answer:

I don't know the answer to this but

Suppose we draw a sample of size n=16 from this population and want to know how likely we are to see a sample average greater than 22, that is P( > 22)? So the probability that the sample mean will be >22 is the probability that Z is > 1.6 We use the Z table to determine this: P( > 22) = P(Z > 1.6) = 0.0548.

What are Trigonometric Functions?

Trigonometric functions are those functions which are the ratio of the sides of a right angled triangle.

Given,

sin² (x) = [1 - cos (2x)] / 2

We have to prove sin ([tex]\frac{x}{2}[/tex]) = ± [tex]\sqrt{\frac{1-cos (x)}{2} }[/tex]

First, we have

sin² (x) = [1 - cos (2x)] / 2

Substituting x/2 in place of x, we get,

sin² (x/2) = [1 - cos (2x/2)] / 2

sin² (x/2) =  [1 - cos (x)] / 2

sin² ([tex]\frac{x}{2}[/tex]) = [tex]{\frac{1-cos (x)}{2} }[/tex]

Taking square root on both sides,

sin ([tex]\frac{x}{2}[/tex]) = ± [tex]\sqrt{\frac{1-cos (x)}{2} }[/tex]

Hence it is proved.
