Which is the best approximation for the measure of angle ABC?
qwelly [4]

Answer:

58.3°

Step-by-step explanation:

Missing Information:

In this question the diagram is missing Following are the attachment of diagram of the given question.

As we seen that the vertex c is making the right angle i,e 90°  also there is an acute angle the Hypotenuse: 20 cm and the perpendicular is 10.5 cm

Now we have find the best approximation of the angle ABC used the cosx  trigonometric function.

cos\ x\ =\ \frac{perpendicular}{Hypotenuse} \\

Putting the value of perpendicular and hypotenuse in the previous formula we get

cos\ x\ =\ \frac{10.5\ cm}{20\ cm} \\

x\ =cos^{-1}\  0.525\\x \ = \ 58.33

Solving algebraic equations:<br><br> 5n+1<br><br> What do I do to solve this?
emmainna [20.7K]

Explanation:

The given <em>expression</em> is not an <em>equation</em>. There is nothing that can be <em>solved</em>.

___

An equation has an equal sign between its left side and its right side. Solving it means finding a value for the variable (or variables) such that the equation is true.

For example, we might have ...

  5n +1 = 1

Your familiarity with math facts means you know that ...

  0 +1 = 1

In order for the term 5n to have a value of 0, the value of n must be 0 in this equation. The solution to 5n+1 = 1 is <em>n = 0</em>, because 5×0 + 1 = 1 is a true statement.

___

An <em>expression</em> can be evaluated. To do that, put the value you want the variable to be every place you see the variable, then do the arithmetic.

To evaluate 5n+1 for n=6 we put 6 in place of n:

  5×6 +1

Doing the arithmetic, we get ...

  = 30 +1 = 31

The value of 5n+1 for n=6 is 31.

Name the property shown by the statement. (8 + 7) + 3 = 8 + (7 + 3)
Evgen [1.6K]

Step-by-step explanation:

Associative Property states that you can add or multiply regardless of how the numbers are grouped. By 'grouped', I mean 'how you use parenthesis'. In other words, if you are adding or multiplying it does not matter where you put the parenthesis. Example: 3+(2-4) can be rewritten as (3+2)-4.

hope it helps!
