Trapezoid and kite make up the first split of quadrilaterals on the quadrilateral hierarchy
<h3>What is a
quadrilateral?</h3>
A quadrilateral is a polygon that has four sides and four angles. Types of quadrilateral are<em> square, kite, trapezoid, rectangle, rhombus </em>and so on.
A quadrilateral hierarchy is a graphical way of representing the different types of quadrilaterals.

All I can really remember is find the scale factor and divide it by the segment
Answer:
31.25
Step-by-step explanation:
25/12=2.083333
15 x 2.0833333=31.24999999995
round up to get 31.25
If <em>θ</em> lies in the fourth quadrant, then sin(<em>θ</em>) < 0 and cos(<em>θ</em>) > 0. So we have from the Pythagorean identity,
sin²(<em>θ</em>) + cos²(<em>θ</em>) = 1 ==> cos(<em>θ</em>) = +√(1 - sin²(<em>θ</em>)) = √21/5
Then
sec(<em>θ</em>) = 1/cos(<em>θ</em>) = 5/√21
and
tan(<em>θ</em>) = sin(<em>θ</em>)/cos(<em>θ</em>) = (-2/5)/(√21/5) = -2/√21

Answer:
(a) 75.5
Step-by-step explanation:
There are two ways you can work this.
<u>Pythagorean theorem</u>
Triangle CMP is a right triangle. CM = AC = 55. CP = CB -PB = 55 -15 = 40. Then length PM can be found from ...
PM² +CP² = CM²
PM = √(CM² -CP²) = √(55² -40²) = √1425 ≈ 37.749
The length MN is twice the length of PM, so is ...
MN = 2×PM = 2×37.349 = 75.498
The length of MN is about 75.5.
__
<u>Using chord relationships</u>
The products of the different lengths for the same chord are the same for the crossed chords.
AP×PB = MP×PN
We know MP = PN, so ...
MP = √(AP×PB) = √((55+40)(15)) = √1425
As before, MN = 2×MP = 2√1425
MN ≈ 75.5
