Equation of a line that is perpendicular to given line is $y=\frac{-7}{4} x+\frac{7}{4}$ .

Equation of a line that is parallel to given line is $y=\frac{4}{7} x-\frac{69}{7}$ .

Solution:

Given line $y=\frac{4}{7} x+4$ .

Slope of this line, $m_1$ = $\frac{4}{7}$

$$\text{Slope of perpendicular line} = \frac{-1}{\text{Slope of the given line} }$

$$m_2=\frac{-1}{m_1}$

$$=\frac{-1}{\frac{4}{7} }$

Slope of perpendicular line, $m_2=\frac{-7}{4}$

Passes through the point (–7, 5). Here $x_1=-7, y_1=5$ .

Point-slope formula:

$y-y_1=m(x-x_1)$

$$y-(-7)=\frac{-7}{4} (x-5)$

$$y+7=\frac{-7}{4} x+\frac{35}{4}$

Subtract 7 from both sides, we get

$$y=\frac{-7}{4} x+\frac{7}{4}$

Equation of a line that is perpendicular to given line is $y=\frac{-7}{4} x+\frac{7}{4}$ .

To find the parallel line:

Slopes of parallel lines are equal.

$m_1=m_3$

$$m_3=\frac{4}{7}$

Passes through the point (–7, 5). Here $x_1=-7, y_1=5$ .

Point-slope formula:

$$y-(-7)=\frac{4}{7} (x-5)$

$$y+7=\frac{4}{7} x-\frac{20}{7}$

Subtract 7 from both sides,

$$y=\frac{4}{7} x-\frac{69}{7}$

Equation of a line that is parallel to given line is $y=\frac{4}{7} x-\frac{69}{7}$ .

Determine if the triangles are similar. If similar, state how and complete the similarity statement.

Ray Of Light [21]

Answer:

Step-by-step explanation:

so all the angles of a triangle add up to 180 degrees

180-42-62= 76

so we know angle TUS is 76 degrees

the other triangle has an angle of 78 degrees which isn't 42, 62, or 76.

The triangles are not similar because similar shapes have congruent angles

6x+40=4x-44 please help

cestrela7 [59]

Answer:

$6x+40=4x-44$

$6x - 4x = - 44 - 40$

$2x = -84$

$x = \frac{ - 84}{2}$

$x = - 42$

Find the value of x (explain if you can because I don’t understand geometry that well).

VLD [36.1K]

Answer:

the degree of x can be added to 120 to get 180. they form a straight line which is 180°. subtract 120 from 180 to get you answer.

180-120=60 so x=60
