Since it's a Trapezoid with its non - parallel sides equal to one another,

$\qquad \sf \dashrightarrow \:\angle A + \angle P = 180$

[ By forming co - interior angle pair ]

$\qquad \sf \dashrightarrow \:\angle A +100 = 180$

$\qquad \sf \dashrightarrow \:\angle A = 180 - 100$

$\qquad \sf \dashrightarrow \:\angle A = 80$

Now, similarly,

$\qquad \sf \dashrightarrow \:\angle A + \angle R = 180$

$\qquad \sf \dashrightarrow \: \angle R + 80 = 180$

$\qquad \sf \dashrightarrow \: \angle R = 100$

Similarly,

$\qquad \sf \dashrightarrow \angle K + \angle R = 180$

$\qquad \sf \dashrightarrow \angle K + 100 = 180$

$\qquad \sf \dashrightarrow \angle K = 80$

An experiment was conducted, and it was determined that plants that received more than two hours of sunlight per day grew larger

natka813 [3]

Answer:

A) Based on the data, this is an example of correlation and causation.

Step-by-step explanation:

The correlating item is the sunlight

The causation is the growth vs. non growth: The sunlight caused growth. The lack of sunlight caused the plants not to grow as fast.

Which is an equation of the line that passes through<br> the points (5, 2) and (10, -3)?

sashaice [31]

Answer:

y = -x + 7

Step-by-step explanation:

Hi there!

We are given the following points:
(5,2) and (10,-3)

We want to find the equation of the line that passes through these 2 points

There are 3 ways to write the equation of the line, yet the most common way is slope-intercept form, which is y=mx+b (m is the slope and b is the y intercept).

First, let's find the slope of the line.

The slope can be calculated from 2 points using the equation $\frac{y_2-y_1}{x_2-x_1}$ , where $(x_1, y_1)$ and $(x_2, y_2)$ are points

We have everything we need to find the slope, but let's label the values of the points to avoid confusion and mistakes.

$x_1=5\\y_1=2\\x_2=10\\y_2=-3$

Now substitute these values into the formula to find the slope

m= $\frac{y_2-y_1}{x_2-x_1}$

m= $\frac{-3-2}{10-5}$

Simplify

m= $\frac{-5}{5}$

Divide

m=-1

The slope of the line is -1

We can substitute this value as m in y=mx+b.

Here's the equation of our line so far:

y=-x+b

Now we need to find b

As the equation passes through the points (5,2) and (10,-3), we can use either point to find the value of b

Taking (5,2) for example:

Substitute 5 as x and 2 as y

2=-5+b

Add 5 to both sides

7=b

Substitute 7 as b in the equation

y = -x + 7

Hope this helps!
