Answer with explanation:

It is given that the triangle has three sides having  side length 2, 2 and 3 units.

Since two sides of triangle is equal, So it is an Isosceles triangle.

To check whether it has any of the angle is right angle or Obtuse angle, we will use Cosine formula.

Since Angle Opposite to Larger side is greater.Angle Opposite to Larger side 3 units be m°.

\cos m=\frac{2^2+2^2-3^2}{2\times2 \times 2}\\\\\cs m=\frac{4+4-9}{8}\\\\ \cos m=\frac{-1}{8}

⇒→Since , cosine of angle between  two sides ,2 and 2 is , Negative.It means it is an Obtuse Angle.

So, other two angles will be acute.

So, the given triangle having sides 2,2,and 3 is Obtuse Isosceles Triangle.

Write the equation of the line in slope-intercept form passing through the points (-4,2) and (1,12)
alexira [117]

Answer:

y = 2x + 10

Step-by-step explanation:

Find the slope:

12 - 2 / 1 - (-4)

10 / 5 = 2

Write in point-slope form:

y - 12 = 2(x - 1)

rearrange:

y - 12 = 2x - 2

y = 2x + 10
