Step-by-step explanation:

The sum of the interior angles of a triangle is equal to 180°. So from the figure, we can see that

$m + 2m + (m + 10) = 180$

Collecting all similar terms, we get

$4m + 10 = 180 \Rightarrow 4m = 170$

or

$m = 42.5°$

So the angle measures are now as follows:

$m = 42.5°$

$2m = 85°$

$m+ 10 = 52.5°$

Answer:

Option D: - 6; $\textbf{-5}\frac{\textbf{5}}{\textbf{2}}$ ; $\textbf{-4}\frac{\textbf{1}}{\textbf{5}}$ .

Step-by-step explanation:

The sequence is defined by:

$A(n) = -6 + (n - 1)\bigg( \frac{1}{5} \bigg )$

To find the first term of the sequence simply substitute n = 1.

First term of the sequence:

$A(1) = -6 + (1 - 1)\bigg( \frac{1}{5} \bigg )$

$= - 6$

Fourth term of the sequence:

$A(2) = -6 + (4 - 1) \bigg ( \frac{1}{5} \bigg)$

$= - 6 + 3\bigg( \frac{1}{5} \bigg)$

$= \frac{- 30 + 3}{5}$

$= \frac{-27}{5}$

$= \frac{-25 - 2}{5}$

$= - 5 - \frac{2}{5}$

$= -5\frac{2}{5}$ is the required answer.

Tenth term of the sequence:

$A(10) = - 6 + (10 - 1) \bigg( \frac{1}{5} \bigg)$

$= - 6 + 9\bigg( \frac{1}{5} \bigg)$

$= \frac{-30 + 9}{5}$

$= \frac{-21}{5}$

$= \frac{-20 - 1}{5}$

$= - 4 - \frac{1}{5}$

$= -4\frac{1}{5}$ is the required answer.

What is 2 1/8 in improper fraction form? *<br> I need help now!!!!!!

KengaRu [80]

Answer:

17/8

Step-by-step explanation:

Step 1: Multiply the whole number part (2) by the denominator (8).

2 × 8 = 16

Step 2: Add the product from Step 1 (16) to the numerator (1).

16 + 1 = 17

Step 3: Write that result (17) above the denominator. So,

2 1/8

= 17/8
