Answer:

Trapzoid

Step-by-step explanation:

Given: A (-2, 3), B (9, 3), C (5, 6) and D (2, 6)

We will find the slope of each line.

Formula:

\text{Slope, m}=\dfrac{y_2-y_1}{x_2-x_1}

\text{Slope of AB, m}_1=\dfrac{3-3}{9+2}=0

\text{Slope of BC, m}_2=\dfrac{6-3}{5-9}=-\dfrac{3}{4}

\text{Slope of CD, m}_3=\dfrac{6-6}{2-5}=0

\text{Slope of AD, m}_4=\dfrac{6-3}{2+2}=\dfrac{3}{4}

Slope of AB = Slope of CD = 0

m_1=m_3=0

Thus, AB is parallel to CD

Slope of BC ≠ Slope of AD

m_2\neq m_4

Thus, BC is not parallel to AD

The quadrilateral ABCD has two sides are parallel and two are not parallel.

Hence, The quadrilateral is trapzoid

The quadrilateral ABCD, with vertices <span>A(-2,3), B(9,3), C(5,6) and D(2, 6), is a trapezoid. 

 By definition, a trapezoid is a quadrilateral which has two parallel sides (These are called "bases"), but the other sides are not parallels. </span>

K^2+8k-9=0 can you help me solve with showing work
givi [52]
Using the PSN method:

P = -9
S = 8
So N = 9,-1

Using 9 and -1 in the original equation gives:

k^2+9k-k-9=0&#10;\\k(k+9)-1(k+9)=0&#10;\\(k-1)(k+9)&#10;&#10;\\\\k=1,-9

If OQ and RT are parallel lines and mZRSP = 55°, what is mZQPS?
bogdanovich [222]

Answer:

55 degrees

Step-by-step explanation:

Angles RSP and QPS are Alternate Interior Angles. Given that OQ and RT are parallel, alternate interior angles are always congruent, meaning they have the same measure.

So if angle RSP is 55 degrees and it is congruent to angle QPS, then angle QPS is 55 degrees.
