Alright, lets get started.

Please take a look at the diagram attached.

The reference angle of 75 will be 75

As it is mentioned that the angle intersects the unit circle means r = 1

So, finding cos

cos 75 = \frac{X}{r}

cos 75 = \frac{0.259}{1}

cos 75 = 0.259    :   Answer

Hope it will help :)

A 12-foot flagpole casts a nine-foot shadow. What is the measure from the top of the shadow to the top of the flag pole?
amm1812

Here is the answer OwO:

A 12-foot flagpole casts a nine-foot shadow. The measure from the top of the shadow to the top of the flag pole is 15.

Here is the explanation/work OwO:

<u><em>Switch sides.</em></u>

c^2=12^2+9^2

<u><em>12^2=144</em></u>

c^2=144+9^2

<u><em>9^2=81</em></u>

c^2=144+81

<u><em>Add the numbers: 144 + 81 = 225</em></u>

c^2=225

<u><em>For x^2 = f(a) the solution is √f(a)</em></u>

c = 15

Therefore, your answer will be 15.

What is a percentage? What do we do with percentages?
Marianna [84]

Answer:

percentages are used like fractions and decimals, as ways to describe parts of a whole. For example, discounts in shops, bank interest rates, rates of inflation and many statistics in the media are expressed as percentages. Percentages are important for understanding the financial aspects of everyday life. When you are using percentages, the whole is considered to be made up of a hundred equal parts. The symbol % is used to show that a number is a percentage, and less commonly the abbreviation 'pct' may be used.
