Look at this triangle.
B
8 cm
A
22 cm
Work out length AB.

Answers

Answer 1

Answer:

23.41cm

Step-by-step explanation:

Using Pythagoras theorem

a²+b² = c²

Where a and b are sides of the triangle and c is the Hypotenuse.

If we substitute the values

B= 8 cm

A= 22 cm

22²+8² = c²

484 + 64= c²

√548 = c

C= 23.41

Hence, length AB is 23.41cm

csc^-1 4.25 to degrees​

Answers

9514 1404 393

Answer:

  13.609°

Step-by-step explanation:

The csc^-1 function is the arccosecant function. It gives the angle whose cosecant is given. If we let A represent that angle, your statement is ...

  A = csc^-1(4.25)

It is used to solve the relation ...

  4.25 = csc(A)

__

Some calculators can give you the value directly (see attached). Most cannot. In any event, you need to make sure the angle mode for the calculator is set to degrees.

When your calculator does not have the csc^-1 function, you can make use of the trig identity ...

  csc(x) = 1/sin(x)

In the above equation, this becomes ...

  4.25 = 1/sin(A)

  sin(A) = 1/4.25 . . . . . solve for sin(A)

All scientific and graphing calculators will have the inverse sine (arcsine) function.

  A = sin^-1(1/4.25)

  A ≈ 13.609° . . . . . . . calculator mode in Degrees

_____

Additional comment

For inverse functions, especially inverse trig functions, I find it useful to read them as ...

  csc^-1(x)   ⇒   "the angle whose cosecant is x"

  sin^-1(x)   ⇒   "the angle whose sine is x"

This reminds me that the value it gives is an angle (degrees or radians), and the argument it takes is a pure number (one with no units).

A bird can lay either white or brown eggs. Three white eggs
and
two brown eggs have a mass of 13 grams, while five white eggs
and four brown eggs have a mass of 24 grams. Find the mass
of a brown egg and of a white egg.

Answers

Answer:

Mass of brown egg = 3.5 grams

Mass of white egg = 2 grams

Step-by-step explanation:

Let

Mass of brown eggs = x

Mass of white eggs = y

3y + 2x = 13 (1)

5y + 4x = 24 (2)

Multiply (1) by 5 and (2) by 3 to eliminate y

15y + 10x = 65 (3)

15y + 12x = 72 (4)

Subtract (3) from (4)

12x - 10x = 72 - 65

2x = 7

x = 7/2

x = 3.5

Substitute x = 3.5 into (1)

3y + 2x = 13 (1)

3y + 2(3.5) = 13

3y + 7 = 13

3y = 13 - 7

3y = 6

y = 6/3

y = 2

Mass of brown egg = 3.5 grams

Mass of white egg = 2 grams

Step-by-step explanation:

2: 1.50+x=π This problem is impossible.  This is because Pi is a number that goes for infinitiy so there is no answer for x.  This also means ∞ can also be an answer.

Answer:

1. 9

2.

Step-by-step explanation:

1. Mara has $640 in her bank account, she withdraws $30 each month. We don't know how many months will she withdraw until 370$. Let's write an expression first:

640 - 30x = 370

Now, subtract both sides by 640 to get -270:

-30x = -270

Last, divide both side by -30:

-30x = 270

x = 9

Now, we know she withdraws $30 for 9 months.

2. 2 + 4(3 - 2) = x

   This tells us that we do not know the answer until we solve it.

   2 + 4(3 - 2) = x

   2 + 12 - 8 = x

   6 = x

2) Select one of your sides.
