Answer:

x = 7

Step-by-step explanation:

The 2 marked angles are Alternate exterior angles ( they are outside the parallel lines ) and are congruent, that is

10x = 9x + 7 ( subtract 9x from both sides )

x = 7

Answer:

x = 7.

Angle = 70 degrees.

Step-by-step explanation:

These 2 angles are exterior alternate angles and so they are equal.

So 9x + 7 = 10x

Subtract 7 from both sides:

9x + 7 - 7 = 10x - 7

9x = 10x - 7

Subtract 10x from both sides:

9x - 10x = 10x -10x - 7

-x = -7

x = 7

The measure of the angle = 10x

= 10*7

= 70 degrees.

Indicate the equation of the given line in standard form. The line through (2, -1) and parallel to a line with slope of 3/4

Ket [755]

Well, for a line with a slope of 3/4, any other parallel line to it, will also have the same slope of 3/4

so if the line through (2, -1) is parallel to it, it has a slope of 3/4 as well

$\bf \begin{array}{lllll}
&x_1&y_1\\
% (a,b)
&({{ 2}}\quad ,&{{ -1}})\quad 

\end{array}
\\\\\\
% slope = m
slope = {{ m}}= \cfrac{rise}{run} \implies \cfrac{3}{4}
\\\\\\
% point-slope intercept
y-{{ y_1}}={{ m}}(x-{{ x_1}})\qquad 
\begin{array}{llll}
\textit{plug in the values for }

y_1=-1\\
x_1=2\\
