    <em>Find the slope using the following points:</em>

<em>         (20, -10) (6, -20)</em>

<em />

<em />\rule{50}{1}\large\blue\textsf{\textbf{\underline{Answer and how to solve:-}}}

Use the slope formula:-

                    \LARGE\text{$\displaystyle\frac{y_2-y_1}{x_2-x_1}$}

Replace letters with numbers as follows:-

                             \Large\text{$\displaystyle\frac{-20-(-10)}{6-20}$}

On simplification,

                                  \Large\text{$\displaystyle\frac{-20+10}{-14}$}

On further simplification,

                                        \Large\text{$\displaystyle\frac{-10}{-14}$}

Reducing the fraction,

                               \large\text{$\displaystyle\frac{10}{14}$}

               \large\text{$\displaystyle\frac{5}{7}$}\leftarrow\:slope

<h3>Good luck with your studies.</h3>

I need some help please​
Mama L [17]

Answer:

109

Step-by-step explanation:

Formula

<ZHG + <IHZ = <IHG

Givens

<ZHF = 11x - 1

<IHZ = 24

<IHG = 12x + 13

Solution

11x - 1 + 24 = 12x + 13             Combine terms on the left

11x + 23 = 12x + 13                  Subtract 13 from both sides

<u>      - 13             - 13  </u>

11x + 10 = 12x                           Subtract 11x from both sides

<u>-11x           -11x</u>

        10 =   x

Answer

11x - 1 = 11*10 - 1 = 110 - 1 = 109

Help. Can somebody help me with this. Thank you.

Answer:

m\angle CAB=65^\circ

Step-by-step explanation:

<u>Angles and Lines</u>

It's convenient to recall two basic principles of angles:

The sum of internal angles in a triangle is 180°

Two linear angles are supplementary, i.e. they sum 180°.

Angles ABC and CBD are linear. Since we know the measure of angle CBD, thus the measure of angle ABC is 180°-6x.

Now focus on the triangle. The sum of its internal angles is:

x + 40 + 3x + 10 + 180 - 6x = 180

Simplifying:

-2x + 230 = 180

Subtracting 230:

-2x = -50

Dividing by -2:

x = -50 / (-2) = 25

x = 25°

Now find the measure of angle CAB

m\angle CAB=x+40=25+40=65

\mathbf{m\angle CAB=65^\circ}
