Answer: x=50°
Step-by-step explanation:
For this question, you have to first find out whether you are using Sin, Cos or Tan.
To help you find out which one you are using you can use SOH CAH TOA to help you:
SOH-the 'S' is for Sin then the 'O' and the 'H' is for Opposite over Hypotenuse.
CAH-the 'C' is for Cos and then the 'A' and the 'H' is for Adjacent over Hypotenuse.
TOA-the 'T' is for Tan then the 'O' and the 'A' is for Opposite over Adjacent.
In this, because you have the Hypotenuse (the length opposite the right angle) and the Adjacent (the length next to the angle you are finding) you would be using Cos.
So first you would write:
Cos x=59/91
But then because you want x on it's own you would do the inverse. So, instead of multiplying x by cos you would have to do cos-1 (the inverse of cos). This would be written as:
x=cos-1 59/91
To get the answer you would have to put this in your calculator.
So x=50°

9. If AJKL - ANML, find the values of x and y.
Answer:
x = 35, y = 18
Step-by-step explanation:
Since both triangles are similar, their sides must be proportional with means all of them have a common ratio.
If NM = 16, and KJ = 40. 40/16 is the ratio from ∆NML to ∆JKL. The reciprocal(numerator and denominator flip, the product of a number and it's reciprocal is 1) of this is true from ∆JKL to ∆NML.
Now to find the missing sides you multiply a side by the common ratio to find it's corresponding side length.
Dividing by a number is the same as multiplying by the reciprocal of that number.
40/16 can be reduced to 5/2 or 2 ½ as a mixed fraction.
16/40 can be reduced to 2/5 or 0.4 as a decimal.
Since the scale of ∆JKL is greater than ∆NML, you multiply by 5/2 to get the corresponding side of ∆JKL from ∆NML.
Since the scale of ∆NML is less than ∆JKL, you multiply by 2/5 to get the corresponding side of ∆NNL from ∆JKL.
Therefore x = 14 × 5/2 = 70/2 = 35.
y = 45 × 2/5 = 90/5 = 18.

A matea le encanta dibujar barquitos.Si traslado su barquito inicial 1 des veces,(2 y 3) ¿Cómo desplazo cada uno de sus puntos?
Answer:
Luego de una búsqueda online, encuentre más información sobre esta pregunta, la cual se puede ver en la imagen del final.
Básicamente lo que tenemos que hacer en este tipo de problemas, es estudiar como los puntos del barco uno cambian cuando hacemos cada transformación, usualmente con un par de puntos ya podremos notar un patrón, y de esta forma entender la transformación que utilizo para mover la figura.
Para conocer las coordenadas de cada punto tenemos que ver el valor de x asociado (el eje horizontal) y el valor de y asociado (el eje horizontal), notar que cada punto está representado por una letra, esto nos permite asociar a los puntos de los distintos barcos.
Entonces, en la transformación de (1) a (2), los cambios en los puntos son:
A (1, 7) --> A₁ (11, 11) (sumamos 10 al eje x, sumamos 4 al eje y)
B (0, 9) --> B₁ (10, 13) (sumamos 10 al eje x, sumamos 4 al eje y)
C (3 , 9) --> C₁ (13, 13) (sumamos 10 al eje x, sumamos 4 al eje y)
Ok, ya con 3 puntos podemos notar un patrón, sea (x, y) un punto cualquiera en el barco (1), el correspondiente punto en el barco (2) va a ser (x + 10, y + 4), esta es la regla utilizada para mover el barco de (1) a (2), lo que es equivalente a decir que movió el barco 10 unidades a la derecha, y 4 unidades para arriba.
Ahora Mateo vuelve a mover el barco, esta vez de (2) a (3).
De vuelta, tenemos que ver como los puntos del barco (2) cambian, y tratar de encontrar un patrón:
A₁ (11, 11) --> A₂ (9, 1) (restamos 2 en el eje x, restamos 10 en el eje y)
B₁ (10, 13) --> B₂ (8, 3) (restamos 2 en el eje x, restamos 10 en el eje y)
C₁ (13, 13) --> C₂ (11, 3) (restamos 2 en el eje x, restamos 10 en el eje y)
De vuelta, ya tenemos suficiente información como para notar el patrón, para un punto (x, y) del barco (2), el correspondiente punto en el barco (3) se escribe como (x - 2, y - 10).
Es decir, movemos el barco (2) 2 unidades para la izquierda y 10 unidades para abajo, asi llegando al barco (3).

What do I do in this problem?
Answer: p=60
Step-by-step explanation:
Angles on a straight line always add up to 180 degrees.
So, because you have an angle on the straight line with the arrow going up, you have to do:
180-110=70
This will give you the angle inside of the triangle that is next to 110.
Then you would find the angle next to 130 (using the horizontal line) by using the same method so you would do:
180-130=50
This gives you the angle inside the triangle next to 130.
Then because a triangle always adds up to 180 you would add up the 2 angles you have figured out like this:
70+50=120
Then you would take the answer away from 180 like this:
180-120=60
So, p=60
Hope this helps :)
Two trains started moving at the same time, train A from Boston to New York, and train B from New York to Boston. The distance between the train stations in New York and Boston is 240 miles. The average speed of train A is 60 mph, which is 3 4 of the average speed of train B.
1. How soon will the trains meet
2. How far from New York will the trains meet?
Answer:
------
Step-by-step explanation:
1. The average speed of train A = 60 mph,
The average speed of train B = 60 / 3/4 = 80 mph
Time it takes for trains to meet = 240/(60 + 80) = 240/140 = 12/7 hours
2. The trains meet in 12/7 hours, each traveling at their own speed.
S = D/T, D = S*T
Therefore we can say:
12/7(60) = distance train A is from Boston = 720/7 miles
12/7(80) = distance train B is from New York = 960/7 miles
The distance from New York would = 960/7 miles

You buy a new video game for $60.
The sales tax is 8%.
What is the total cost for the game including sales tax?
Answer:
$64.8
Step-by-step explanation:
To determine the tax, you want to make the percent into a decimal by moving the decimal point over two times the the left, which means 8% would be 0.08. Then, multiply the new decimal by the price. 60 times 0.08 is 4.8. Now, add the tax to the original price. 60+4.8=64.8, so therefore the total cost is $64.8

Elena bowls two games on Saturday. Her score in the second game is 30 more than ¾ of her score the first game. Elena's total score for the two games is 478. Write and solve an equation to demonstrate the points scored in her second game.
Answer:
222 = score in 2nd game
Step-by-step explanation:
Let x = score in 1st game
3/4(x) + 30 = score in 2nd game
x + 3/4(x) + 30 = 478 Multiply thru by 4 to eliminate the fraction
4x + 3x + 120 = 1912
7x + 120 = 1912
7x = 1792
x = 256
3/4(x) + 30 = 3/4(256) + 30
= 192 + 30
222 = score in 2nd game
Check: 222 + 256 = 478

The temperature of chicken soup is 192.7°F. As it cools, the temperature of the soup decreases 2.3°F per minute. What is the temperature in degrees Fahrenheit of the soup after 25 minutes?
Answer: 135.2 °F
Step-by-step explanation:
The temperature decreases at a rate of 2.3 °F per minute.
This means that in 25 minutes, the temperature would have reduced by:
= 2.3 * 25
= 57.5°F
If the original temperature was 192.7 °F, the temperature after 25 minutes will be:
= 192.7 - 57.5
= 135.2 °F
