What are trigonometric ratios in terms of a right-angle triangle?

We know a right-angled triangle has three sides they are -: Hypotenuse,

Opposite and Adjacent.

We can remember SOH CAH TOA which is,

sin = opposite/hypotenuse, cos = adjecen/hypotenuse and

tan = opposite/adjacent.

Given, The vertical or opposite distance is 2 feet and it has an angle of 5°.

∴ The horizontal or adjacent distance can be obtained by tan(theta).

Assuming horizontal distance to be x feet.

∴ tan(5°) = 2/x feet.

x = 2/tan(5°).

x = 22.9 feet.

Lucy is laying tile around the edge of a counter that is 6.4 feet by 2.7 feet. If each tile is 6 inches long, and Lucy buys 30 tiles, will she have enough to line the edge of the counter top?

Answers

Answer:

Tiles won't be enough

Step-by-step explanation:

The perimeter of the area :

2(length + Width)

Given dimension = 6.4 by 2.7 feets

Perimeter = 2(6.4 + 2.7) = 18.2 feets

1 feet = 12 inches

Perimeter = 18.2 * 12 = 218.4 inches

1 tile = 6 inches

30 tiles = 6* 30 = 180 inches

Since the perimeter of the area is greater Than the 180, then we can conclude that the tiles won't be enough

. Nine people are going to share a 128-ounce bottle of soda. How many ounces will each person get to drink? Choose the correct equation and answer for this situation.

Answers

Answer:

[tex]Each = 14.22\ oz[/tex]

Step-by-step explanation:

The options are missing. However, the question is still solvable

Given

[tex]People = 9[/tex]

[tex]Soda = 128\ oz[/tex]

Required

Determine the amount each person will drink

To do this, we simply divide the size of the soda by the number of people.

[tex]Each = \frac{Soda}{People}[/tex]

[tex]Each = \frac{128\ oz}{9}[/tex]

[tex]Each = 14.22\ oz[/tex]

Answer:

14 2/9 ounces

You count 100 chirps in 1 minute. What is the temperature?

Answers

Answer:

T = 50 + 100 - 40/4

T = 50 + 60/4

T = 50 + 15

T = 65

96 = 50 + x - 40/4

Subtract 50 from both sides:

46 = x - 40/4

Multiply by 4:

184 = x - 40

Add 40:

224 = x

Well, birds don't tend to like certain temperatures, and there seemed to be a lot of chirping, so I assume the temperature is the temperature a bird would like.
