Answer:

GIVEN :-

∠A = 15°Length of AB (hypotenuse) = 60 ft

TO FIND :-

Length of BCLength of ACArea of ΔABC

FACTS TO KNOW BEFORE SOLVING :-

[tex]\sin \theta = \frac{Side \: opposite \: to \: \theta}{Hypotenuse}[/tex][tex]\cos \theta = \frac{Side \: adjacent \: to \: \theta}{Hypotenuse}[/tex]

SOLUTION :-

In ΔABC ,

[tex]\sin 15 = \frac{BC}{60}[/tex]

[tex]=> 0.2588... = \frac{BC}{60}[/tex]

[tex]=> BC = (0.2588....) \times 60 = 15.5291.....[/tex] ≈ 15.5 ft

Step-by-step explanation:

For the first one, distribute -11 to each value. A negative times a negative is a positive, so -11×-2c is 22c. -11×-3d is 33d. So the first one is right. For the third one, distribute 1/3 to each value. 1/3 of 66c is 22c, and 1/3 of 99d is 33d, so the third one is correct as well. For the last one, distribute 11 again. 11×2c is 22c and 11×3d is 33d, so the last one is correct.

Answers

Answer:

100

Step-by-step explanation:

because 4, 3, and 2 all make 180 and 4 and 2 are both 40 so you add that which makes 80 and then you take 180 and subtract 80 which gives you 100

Answer:

100

Step-by-step explanation:

This is because angle 1 and angle 2 are congruent, so both of them are 40 degrees. To find angle 3, you do 40+40 which is 80. You then subtract 180-80=100. This is because angles 1, 2, and 3 are all on 1 straight line.

Si un rombo tiene un lado con medida de 16 pulgadas. Cual es su perimetro . If a rhombus has a side measured 16 inches. What is its perimeter.

Answers

Answer:

64 inches or 64 pulgadas

Step-by-step explanation:

The formula for the perimeter of a rhombus is given as:

P = 4a

Where a = side length of the rhombus

From the above question, side length of the rhombus = 16 inches

Hence, Perimeter of the rhombus = 4 × 16 inches

= 64 inches

La fórmula para el perímetro de un rombo se da como:

P = 4a

Donde a = longitud del lado del rombo

De la pregunta anterior, la longitud del lado del rombo = 16 pulgadas

Por lo tanto, perímetro del rombo = 4 × 16 pulgadas

= 64 pulgadas

The cafeteria is preparing ofr lunch. They have 18 bottles of ketchup that hold 96 ounces each. All of the ketchup needs to be divided equally into small containers that hold 1/5 of an ounce each. Hom many small containers are needed for each bottle of ketcup

Answers

Answer:

480 small containers

Step-by-step explanation:

From the above question,

1/5 ounce of ketchup = 1 small container

96 ounces of ketchup = x small containers

Cross Multiply

1/5 ounce × x = 96 ounces × 1

x = 96 ounces × 1/ 1/5 ounce

x = 96 ÷ 1/5

x = 96 × 5/1

x = 480 small containers

Therefore, the number of small containers needed is given as: 480 small containers.

40, degrees. Nuha needs to push it the rest of the way.

Answers

Answer:

The answer is A

Step-by-step explanation: BIG BRAIN

The equation that will tell us the measure of the additional angle, a, that Nuha needs to push the door before she can get out is D: 160 - 40 - a.

To determine the equation that will give us the measure of the additional angle, a, that Nuha needs to push the door before she can get out, we can break down the information provided:

1. The door needs to rotate 160° for Nuha to pass through.

2. The wind pushed the door 40°.

To find the additional angle that Nuha needs to push the door, we can subtract the angle already rotated (40°) and the angle she needs to pass through (160°) from the total rotation angle:

Total rotation angle = Angle already rotated + Angle Nuha needs to push + Additional angle Nuha needs to push

Based on this equation, we can eliminate options A, B, and C since they do not accurately represent the situation.

The correct equation is option D: 160 - 40 - a. This equation represents subtracting the angle already rotated (40°) and the angle Nuha needs to pass through (160°) from the total rotation angle, leaving the additional angle (a) that Nuha needs to push the door.
