I’m stuck with this question plz help

Given:

The figure of a right angle triangle.

To find:

The length of the line segment AC.

Solution:

In a right angle triangle,

[tex]\tan \theta=\dfrac{Opposite}{Adjacent}[/tex]

In the given right triangle ABC,

[tex]\tan (A)=\dfrac{BC}{AC}[/tex]

[tex]\tan (55^\circ)=\dfrac{BC}{AC}[/tex]

[tex]\tan (55^\circ)=\dfrac{15}{AC}[/tex]

[tex]AC=\dfrac{15}{\tan (55^\circ)}[/tex]

On further simplification, we get

[tex]AC=\dfrac{15}{1.428148}[/tex]

[tex]AC=10.503113[/tex]

[tex]AC\approx 10.5[/tex]

The length of side AC is equal to 10.5 m .

Therefore, the correct option is A.

Answer:

seems like the main concept being tested here is unit conversion.

First, let's look at converting kilometers to meters. In the metric system, the prefix "kilo" means 1000. So,

1 kilometer = 1000 meters.

Then, let's look at converting from hours to seconds. As you may know, there are 60 minutes in an hour, and 60 seconds in a minute. So, in 1 hour there are

1 hour*(60 minutes/hour)*(60 seconds/minute) = 3600 seconds.

So, we can use these unit conversion factors to solve your question. Let's convert the units!

9 km/hr = 9 km/hr * (1000 m/km) * (1 hr/ 3600 sec) = 2.5 m/s

Hope this helps!

Answer:

B. [tex]\frac{67}{10} x + 9[/tex]

Step-by-step explanation:

Simplify the expression. Remember to go by the order of operations, or PEMDAS.

1) First, distribute the numbers outside of the set of parentheses to the terms inside the set of parentheses next to them. Then, simplify the fractions.

[tex]3(\frac{7}{5} x + 4) -2 (\frac{3}{2} -\frac{5}{4} x)[/tex]

[tex]\frac{21}{5}x + 12 - \frac{6}{2} + \frac{10}{4} x[/tex]

[tex]\frac{21}{5} x + 12 - 3 + \frac{10}{4} x[/tex]

2) Finally, combine like terms. (This means to add or subtract constants and to add or subtract terms with the same variables.) You may need to convert terms to the same denominator in order to do so easier. Then, reduce the fraction.

[tex]\frac{21}{5} x + 9 + \frac{10}{4}x \\\frac{84}{20}x + \frac{50}{20}x + 9 \\\frac{134}{20}x + 9 \\\frac{67}{10}x + 9[/tex]

Thus, the answer is [tex]\frac{67}{10} x + 9[/tex].

Answer:

B. 67/10x + 9

Step-by-step explanation:

Answer: 1/8

Step-by-step explanation:

From the question, we are informed that a large hose can fill 7/8 of a water tank in one hour while a small hose

can fill 3/4 of a water tank in one hour.

To get the solution to the question above, we have to find the difference between the amount if water filled by the large and the smaller hose. This will be:

= 7/8 - 3/4

= 7/8 - 6/8

= 1/8

Answer:75

Step-by-step explanation: 50+55 =105,

180-105=75

Subscribe to Offxcial Prxmiise

Answer:

x = 105°

Step-by-step explanation:

First to get to know the last angle of the triangle:

[tex]55 + 50 + x = 180 \\ x = 75[/tex]

The last angle of the triangle is 75°

To get the opposite angle we take 180° (the full angle) minus 75° which results in 105°

Answer:

64 + c = 120

Step-by-step explanation:

120 - 64 = 56 t therefore c = 56

The inequality to represent the number of cans, c, that Xander must still collect is c  ≥ 55.

Given the information in the question, the least number of cans that Xander can collet is 120. He can collect more than 120 cans. Thus, the inequality sign to be used is the greater than or equal to sign - ≥.

The number of cans Xander must still collect = 120 - 64 = 55

The inequality solution is c  ≥ 55

Answer:

Para convertir una fracción en un decimal, dividimos el numerador entre el denominador. Si tenemos un número mixto, el número natural se mantiene a la izquierda del punto decimal.

Answer:

Aqui esta la respuesta

Step-by-step explanation:

The line in a fraction that separates the numerator and denominator can be rewritten using the division symbol. So, to convert a fraction to a decimal, divide the numerator by the denominator. If required, you can use a calculator to do this. This will give us our answer as a decimal.

La línea de una fracción que separa el numerador y el denominador se puede reescribir usando el símbolo de división. Entonces, para convertir una fracción en decimal, divide el numerador por el denominador. Si es necesario, puede usar una calculadora para hacer esto. Esto nos dará nuestra respuesta como decimal.

Answer:

circumference = 97.34

Step-by-step explanation:

circumference = diameter x Pi

31 x 3.14 = 97.34 inches

The circumference of the circle with a diameter of 31 inches is approximately 97.34 inches.

The circumference of a circle can be calculated using the formula C = πd, where C represents the circumference and d represents the diameter of the circle.

Given that the diameter of the circle is 31 inches, we can substitute this value into the formula:

C = 3.14 * 31

C ≈ 97.34 inches

Therefore, the circumference of the circle with a diameter of 31 inches is approximately 97.34 inches.

Answer:

x = 10

angle top = 118°

angle bottom = 62°

Step-by-step explanation:

6x + 2 + 11x + 8 = 180

17x + 10 = 180

17x = 170

divide both sides by 17.

x = 10

plug in the 10 to each equation to get the number for the angle

6(10) + 2 = 62°

11(10) + 8 = 118°

Answer:

This is an exponential function

Step-by-step explanation:

f(x)=2(3)^x is one example of the exponential function.  Since f(0) = 2(1) = 2, the y-intercept is (0, 2).  The x-axis is the horizontal asymptote.  The graph begins in Quadrant II, passes through (0, 2) and continues to increase, faster and faster, in Quadrant I.  Next time, please be more specific about what you'd like to know.
