Answer:

False unless a right trapezoid.

Step-by-step explanation:

All trapezoids have 4 angles which add to 360 degrees. The angles can be any measure except in a right trapezoid which does have two 90 degree angles. It is not a requirement to be a trapezoid though so this is false.

What is the slope of a line that is perpendicular to the line shown.
sertanlavr [38]

Answer:

3/4

Step-by-step explanation:

First of all, we need to calculate the slope of the line shown. This can be computed as:

m=\frac{\Delta y}{\Delta x}

where

\Delta y = y_2-y_1 is the increment along the y-direction

\Delta x = x_2 - x_1 is the increment along the x-direction

We can choose the following two points to calculate the slope of the line shown:

(-3,2) and (0,-2)

And so, the slope of the line shown is

m=\frac{-2-(2)}{0-(-3)}=-\frac{4}{3}

Two lines are said to be perpendicular if the slope of the first line is the negative reciprocal of the slope of the second line:

m_2 = -\frac{1}{m_1}

Using m_1 = -\frac{4}{3}, we find that a line perpendicular to the line shown should have a slope of

m_2 = -\frac{1}{-4/3}=3/4

Sindrei [870]

Answer:

Step-by-step explanation:

a = 35 feet

b = 54 feet

h = 28 feet

Area=\frac{[a+b]*h}{2}\\\\=\frac{[35+54]*28}{2}\\\\=\frac{89*28}{2}\\\\=89*14\\\\

= 1246 square feet

Help plz will give brainliest if you explain how u got the answer! PLZ!
sasho [114]

Answer:

2x-y=4

Step-by-step explanation:

y=mx+b

b is the y-intercept which is -4

y=mx-4

find m(slope)

(2,0) and (0,-4)

(-4-0)/(0-2)

-4/-2=2   m=2

y=2x-4

add 4 to both sides

y+4=2x subtract y

4=2x-y

It says write in standard form which looks like this: 3x + 5y = 4
