Answer:

Step-by-step explanation:

The sum of angles in a triangle is 180 degrees. So the third angle in the triangle is

90+32+a=180

a+122=180

a=58

Now angle x is adjacent to angle a so their sum must equal 180 degrees so

x+58=180

x=122 degrees

A square and a rectangle have equal area.The rectangle is 64 cm by 81 cm. What is the perimeter of the square?

Answers

Answer:

2592 cm

Step-by-step explanation:

square area = x²

rectangle area = bh

so

x² = bh

since the areas are equal

b and h are in the problem as 64 and 81

x² = 64x81

x² = 5184

divide by 2

x = 2592 cm

You can use the fact that is irrational to answer the questions below. You can also use other facts proven within this exercise. (a) Prove that is irrational. (b) Prove that is irrational. (c) Is it true that the sum of two positive irrational numbers is also irrational

Answers

Answer:

See Explanation for proofs

Step-by-step explanation:

Given

See attachment for complete question

Solving (a):

[tex]\frac{\sqrt{2}}{2}[/tex] is irrational

[tex]\sqrt{2} =1.41421356237.....[/tex]

So, we have:

[tex]\frac{\sqrt{2}}{2} = \frac{1.41421356237.....}{2}[/tex]

[tex]\frac{\sqrt{2}}{2} = 0.70710678118....[/tex]

[tex]0.70710678118....[/tex] can not be represented as a fraction of whole numbers.

Hence:

[tex]\frac{\sqrt{2}}{2}[/tex] is irrational

Solving (b):

[tex]\sqrt{2} -2[/tex] is irrational

[tex]\sqrt{2} =1.41421356237.....[/tex]

So, we have:

[tex]\sqrt{2} -2 = 1.41421356237..... - 2[/tex]

[tex]\sqrt{2} -2 = -0.58578643763.....[/tex]

[tex]-0.58578643763.....[/tex] can not be represented as a fraction of whole numbers.

Hence:

[tex]\sqrt{2} -2[/tex] is irrational

Solving (c):

The sum of two positive irrational number is always irrational

Proof Below

If a is irrational and b is also irrational,

then

[tex]a + b = irrational[/tex]

Take for instance:

[tex]a = \sqrt{2[/tex]

[tex]b = \sqrt{8[/tex]

[tex]a + b = \sqrt{2} + \sqrt{8[/tex]

[tex]a + b = \sqrt{2} + \sqrt{4*2[/tex]

[tex]a + b = \sqrt{2} + \sqrt{4}*\sqrt{2[/tex]

[tex]a + b = \sqrt{2} + 2\sqrt{2[/tex]

[tex]a + b = 3\sqrt{2[/tex]

[tex]3\sqrt{2[/tex] is irrational and this is true for the sum of every positive irrational numbers

Answers

Step-by-step explanation:

The probability of spinning a one can be written as a fraction. One out of five sections contain a '1' and so, the probability of spinning a one is 1 / 5 . Because 1 is less than half of 5, this outcome can be described as unlikely. The probability of spinning a two is 3 / 5.
