Given:
The vertices of ΔWXY are W(-10, 4), X(-3, -1), and Y(-5, 11).
To find:
Which type of triangle is ΔWXY by its sides.
Solution:
Distance formula:

Using distance formula, we get





Similarly,


Now,

So, triangle is an isosceles triangles.
and,





So, triangle is right angled triangle.
Therefore, the ΔWXY is an isosceles right angle triangle.
Answer:
x = 8
I dunno what the question is in the first place, but I assume you are solving for x.
Step-by-step explanation:
The two given angles are equivalent because they are parallel and they have a line that intersects.
The line creates two angles on each side of each line, which is 120 or 60 because there are 180 degs on a straight line.
The obtuse side is 120, and the -8 + 16x is also on an obtuse angle, showing that they are equal.
120 = -8 + 16x
128 = 16x
8 = x
x = 8
The 2 because we don't know if it is exactly two or if was was rounded up/ down to 2.
Answer:
The second
Step-by-step explanation:
Answer:
y = 4x - 1
Step-by-step explanation:
The line has a slope of 4.
And passes through the point (1,3)
Taking another point (x,y) on the line;
= 4
y - 3 = 4x - 4
y = 4x - 4 + 3
y = 4x - 1
