Which of the following angle measures are possible for a triangle to be classified as scalene? Select all that apply.
RUDIKE [14]

The angle measures that are possible for a triangle to be classified as scalene are:

  • 7∘,160∘,13∘
  • 48∘,71∘,61∘
  • 15∘,52∘,113∘

<h3>What is scalene triangle?</h3>

A scalene triangle  can be described as a  triangle  which consist three sides and all the three sides are of  different lengths, having  all three angles  with different measures.

It should be noted that  the sum of all the interior angles is  equal to 180 degrees.

In conclusion, scalene triangle serves as the  triangle having all three sides  to be in a  different lengths,  and the  three angles  have different measures.

What equation is graphed in this figure?
zzz [600]

Answer:

c. y + 2 = -3(x - 1)

Step-by-step explanation:

By using a point on the line and the slope, we can determine the equation, in point-slope form, that is graphed in the figure.

Using two points, (1, -2) and (0, 1),

slope (m) = \frac{y_2 - y_1}{x_2 - x_1} = \frac{1 -(-2)}{0 - 1} = \frac{3}{-1} = -3

m = -3

Using a point, (1, -2) and the slope (m), we can create an equation for the graph in point-slope form, by substituting x1 = 1, y1 = -2 and m = -3 in y - y_1 = m(x - x_1).

Thus, we would have:

y -(-2) = -3(x - 1)

y + 2 = -3(x - 1)

The equation that is graphed in the figure is:

✔️y + 2 = -3(x - 1)
