What is the value of n?

Answer:

C. 95

Step-by-step explanation:

Start by finding the two other angles in the triangle.

121* and 144* both have supplementary angles in the triangle. This means their counterparts added to them equals 180*

180-121=59 and 180-144=36

These are two of the angles in the triangle. Every triangle's angles add up to 180, so add the two together and then subtract that from 180.

180-(59+36)=180-95=85*

So the angle next to n is 85*. But, this angle and angle n are supplementary as well!

So, 180-85=n

n=95

There's probably other ways to solve this one, but this is how I'd do it. Hope I helped!

PLS HELP ME I’VE ASKED THIS TWICE AND NOBODY HAD ANSWER THIS IS REALLY EASY TO DO
laiz [17]

Answer:

Step-by-step explanation:

All the angles within a triangle equals to 180, and that square thing at a corner of the triangle means that the angle is 90 degrees, so:

20+6x+16+90=180

add stuff

6x+126=180

subtract 126 from both sides

6x=54

divide 6 from both sides

x=9

Write the point-slope form of an equation of the line through the points (-7, 7) and (4, 1).
seraphim [82]

Answer:

Choice B. \displaystyle y - 7 = -\frac{6}{11} \, (x + 7).

Step-by-step explanation:

Start by finding the slope of this line. Let (x_1,\, y_1) and (x_2,\, y_2) represent two distinct points on a line on a Cartesian Plane. (That is, x_1 \ne x_2.) The slope of this line would be:

\displaystyle \frac{y_2 - y_1}{x_2 - x_1}.

For the line in this question:

  • x_1 = -7,
  • y_1 = 7;
  • x_2 = 4,
  • y_2 = 1.

Indeed, x_1 \ne x_2. The slope of this line would thus be \displaystyle \frac{1 - 7}{4 - (-7)}, which is equal to \displaystyle -\frac{6}{11}.

On a Cartesian Plane, the point-slope form of a line that has a slope of m and includes the point (x_0,\, y_0) can be written as:

y - y_0 = m\, (x - x_0).

(Note the minus signs in this form.)

For the line in this question, m = \displaystyle -\frac{6}{11}. There are two equivalent expressions for its point-slope form:

  • Using the first point, y - 7 = \displaystyle -\frac{6}{11}\, (x - (-7)). This equation is equivalent to y - 7 = \displaystyle -\frac{6}{11}\, (x + 7).
  • Using the second point, y - 1 = \displaystyle -\frac{6}{11}\, (x - 4).
