Find tan A. Can someone help me with this one??

Mathematics

Answer:

tan A = 5/12

Step-by-step explanation:

To find tangent of a triangle, it is this ratio : opposite / adjacent.

Knowing that "A" is the given angle, 5 is the opposite and 12 is the side adjacent to "A". Putting these values together, the tangent is

5 (opposite)/12 (adjacent).

Hope this helps!

Can you please show work please
-BARSIC- [3]

Answer:

1) y = 3x+5

2) y =  \frac{1}{2}x-4

3) y = -x + 0

4) y = -\frac{5}{3}x+8

5) y = \frac{3}{5} x - 7

Step-by-step explanation:

y = mx+b

In slope-intercept form, these are important to know:

- y and x should stay as variables

- m = slope of the line

- b = y intercept

Using the facts above⬆, we can solve these problems

Remember: Substitute m and b using the given information

1) y = 3x+5

2) y =  \frac{1}{2}x-4

3) y = -x + 0

4) y = -\frac{5}{3}x+8

5) y = \frac{3}{5} x - 7

Hope this helps :)

Have a great day!

The propeller blades on a submarine have a radius of 6 feet. At full speed, they turn at 120 revolutions per minute. What is the
bogdanovich [222]

Using proportions, it is found that the angular velocity at the tip of the blade is of 753.98 radians per minute.

<h3>What is a proportion?</h3>

A proportion is a fraction of a total amount, and the measures are related using a rule of three.

Each revolution has 2\pi radians, hence in one minute, the 120 revolutions will have a measure in radians of:

M = 120 x 2pi = 240pi = 753.98

Hence the angular velocity is of 753.98 radians per minute.

  • All angles in a triangle add up to 180°

Step-by-step explanation:

<u>Step 1: Set up Equation</u>

x + (x + 65) + 25 = 180

<u>Step 2: Solve for </u><em><u>x</u></em>

  1. Combine like terms:                     2x + 90 = 180
  2. Isolate <em>x</em> term:                               2x = 90
  3. Isolate <em>x</em>:                                        x = 45

149 cars are waiting to take a ferry across the channel. Each ferry can only hold 18 cars. How many cars will be on the last fer
STatiana [176]

Answer:

5 cars will be on the last ferry

Step-by-step explanation:

If you divide 149 by 8, you get 8.27.

Since each ferry can hold 18 cars, you multipy 18 by 8 which results in 144. Then you subtract 144 from 149 and you get 5 :)
