Answer:
Option (B)
Step-by-step explanation:
CDEF is a quadrilateral having vertex C(2, 3), D(1, 2), E(4, 1), F(5, 3).
To prove that the given quadrilateral has a right angle, we will use the property of perpendicular lines.
where and
are the slopes of the consecutive sides of the quadrilateral.
Since CD and DE are the consecutive sides of the quadrilateral, Carla is on the right track by finding the slopes of CD and DE.
Since Jonah is finding the slopes of opposite sides so he will not be able to use the property of perpendicular lines.
Option (B) will be the answer.
Answer: A. 32
Concept:
Here, we need to know the idea of the intersecting chord theorem and segment addition postulate.
The<u> intersecting chord theorem </u>states that when two chords intersect at a point, P, the product of their respective partial segments is equal.
The<u> Segment Addition Postulate</u> states that given 2 points A and C, a third point B lies on the line segment AC if and only if the distances between the points satisfy the equation AB + BC = AC.
If you are still confused, please refer to the attachment below for a graphical explanation.
Solve:
<u>Given information</u>
CW = 12
TW = 14
VW = 2x + 5
UW = 2x + 2
<u>Given expression deducted from intersecting chord theorem</u>
CW · VW = TW · UW
<u>Substitute values into the expression</u>
(12) · (2x + 5) = (14) · (2x + 2)
<u>Expand parentheses and apply the distributive property</u>
24x + 60 = 28x + 28
<u>Subtract 14x on both sides</u>
24x + 60 - 24x = 28x + 28 - 24x
60 = 4x + 28
<u>Subtract 28 on both sides</u>
60 - 28 = 4x + 28 - 28
32 = 4x
<u>Divide 4 on both sides</u>
32 / 4 = 4x / 4
x = 8
<u>Given expression deducted from the segment addition postulate</u>
UT = UW + TW
<u>Substitute values into the expression</u>
UT = 2x + 2 + 14
<u>Substitute x value into the expression</u>
UT = 2 (8) + 2 + 14
UT = 16 + 2 + 14
<u>Combine like terms</u>
UT = 32
