What is the value of x?<br> x = [ ? ]
Mnenie [13.5K]

Answer:

Step-by-step explanation:

The tangent to the angle makes an angle of 90° with the radius.

The interior angle of the equilateral triangle is 60, so that leaves 90-60 = 30° for the remaining angle with the tangent.

By the exterior angle theorem, 30°+x° = 60° (interior angle of the equilateral triangle), therefore

x = 60-30 = 30°.

Write a in slope-intercept form of the line that passes threw (-9,5) and (-3,3)
Amanda [17]

For this case we have that by definition, the equation of a line in the slope-intersection form is given by:

y = mx + b

Where:

m: It is the slope of the line

b: It is the cut-off point with the y axis

m = \frac {y_ {2} -y_ {1}} {x_ {2} -x_ {1}}

We have the following points:

(x_ {1}, y_ {1}): (- 9,5)\\(x_ {2}, y_ {2}): (- 3,3)

Substituting we have:

m = \frac {3-5} {- 3 - (- 9)}\\m = \frac {-2} {- 3 + 9}\\m = \frac {-2} {6}\\m = - \frac {1} {3}

Thus, the equation is of the form:

y = - \frac {1} {3} x + b

We substitute one of the points and find "b":

3 = - \frac {1} {3} (- 3) + b\\3 = 1 + b\\3-1 = b\\b = 2

Finally, the equation is of the form:

y = - \frac {1} {3} x + 2

Answer:

y = - \frac {1} {3} x + 2
