Geometry question confused on how to solve this answer

Mathematics

The acute angles of a right triangle are complementary, so \boxed{m\angle F=34^{\circ}}.

Using right-angle trigonometry, we know that

\cos 56^{\circ}=\frac{26}{DF}\\\\DF=\frac{26}{\cos 56^{\circ}}\\\\\boxed{DF \approx 46.5}

\tan 56^{\circ}=\frac{FE}{26}\\\\FE=26 \tan 56^{\circ}\\\\\boxed{FE \approx 38.5}

How do you Simplify this expression in algebra?<br><br> 9x + 2x (5 + 4) - 2(5x + 4x)
Minchanka [31]

One can solve this by first using order of operations, and then combining like terms.


First is parenthesis


9x + 2x(9) - 2(9x)


Now we do the multiplication


9x + 18x - 18x


Now we combine like terms


9x

Mark had 4 members in his family each of the person get 1/6 what Is the fraction of the tomato use fraction strips
umka21 [38]

If each person got 1/6 then there is still 2/6 left over, =1/3. In fraction strips, we would do

                  1

  1/3         1/3        1/3                                                                 1/3

1/6 1/6   1/6 1/6  1/6 1/6 for the overall tomato and then  1/6 1/6  for the remaining piece of the tomato.

Hope this helps, if you need any more help just comment :)

Simplify 25p^6q^9 / 45p^8q^4. write answer using a positive exponent
sleet_krkn [62]

The simplification of 25p^6q^9 / 45p^8q^4 using a positive exponent;

  • Division is 5p^6 q^9 / 9p^8 q^4
  • Elevated form is  5/9 p^-2 q^5

<h3>What are algebraic expressions?</h3>

Algebraic expressions are expressions made up of factors, variables, terms, coefficients and constants.

They are also comprised of arithmetic operations such as addition, subtraction, multiplication, division, etc

We also know that index forms are also know as standard forms.

They are mathematical expressions showing the power of exponent of a variable in terms of another variable.

Given the index algebraic forms;

25p^6q^9 / 45p^8q^4

Using the rule of indices, we take the negative exponent of the divisor and multiply through.

We have;

5p^6 q^9 × 9p^-8 q^-4

Add exponential values

5/9 p^6-8 q^9 -4

5/9 p^-2 q^5

Thus, the expression is simplified to 5/9 p^-2 q^5
