Answer:
the point is (3, 3) . . . . . . y = 3
Step-by-step explanation:
Write the point-slope equation of the line through the point you know. Then evaluate that equation for x=3 to see what the value of y is.
Point-slope form:
y = m(x -h) +k . . . . slope m through point (h, k)
y = -1/2(x -9) +0 . . . . line with slope -1/2 through point (9, 0)
For x=3, the value of y is ...
y = -1/2(3 -9) + 0 = -1/2(-6) = 3
The value of y is 3.
Answer:
<h2>
x = 19</h2>
Step-by-step explanation:
If the angles of a triangle are 45°, 45° and 90°, the the sides of the triangle are x. x and x√2
x√2 = 19√2 ⇔ x = 19
Answer:
or in decimal form
Step-by-step explanation:
The midpoint of the line with endpoints 
and 
is 
. just take the average between the points
so given the points (1,0) and (2,-10)
the midpoint is found as follows:
or in decimal form
For this case we have that by definition:
A triangle is defined by three lines that are called sides, or by three points called vertices.
We know that:
- <em>The vertices of a triangle are labeled with capital letters.
</em>
- <em>The sides of a triangle are written with lowercase letters.
</em>
- <em>The angles of a triangle are written similarly to the vertices.
</em>
Answer:
The end points of the triangle are called vertices.
They are labeled in capital letters.
