Answer:

<u>The correct answer is A. 21</u>

Step-by-step explanation:

Let's recall that the interior angles of a triangle add up to 180°, therefore, we have this equation:

40 + x + 5x + 14 = 180

6x = 180 - 14 - 40

6x = 126

x = 126/6

x = 21

<u>The correct answer is A. 21</u>

The angles of the triangle are: 40°, 21° and 119°

What pair of fractions is 0.8 between on a number line

madam [21]

0.8 has one decimal.. so... let's make it a fraction first, by using one zero with a one as denominator.

$\bf 0.\underline{8}\implies \cfrac{08}{1\underline{0}}\impliedby \textit{one decimal, one zero, no dot}
\\\\\\
\cfrac{8}{10}\implies \cfrac{4}{5}
\qquad \qquad \qquad 
......\cfrac{1}{5}..\cfrac{2}{5}..\cfrac{3}{5}..\boxed{\cfrac{4}{5}}..\cfrac{5}{5}..\cfrac{6}{5}..\cfrac{7}{5}......$

is between any of those, among many other fractions as well.
