The measure of abc is D. 63 degrees
pogonyaev3 years ago
7 0

Answer:

Option D 63°

Step-by-step explanation:

Two secants AE and CD intersect each other at point B inside the circle.

So by secants theorem,

\frac{m(AC)+m(DE)}{2} = ∠ABC = ∠DBE

= \frac{1}{2} ( 82 + 44 )

= \frac{1}{2} ( 126)

= 63

Option D 63° is the answer.

What is the area of the parallelogram?
Ulleksa [173]

The area of a parallelogram is denoted by b * h, where b is the base and h is the height.

In this case, the b is 15 inches, and the h is 4 inches. Multiply these together and you get: 15 * 4 = 60 square inches.

Find the slope between the two points given. Then, use the slope and one of the points to write the equation of the line in Slop
Anika [276]

Answer:

Equation: y=2x-1

Slope: 2

y-intercept: -1

Step-by-step explanation:

Hi there!

We are given the points (-1, -3) and (-2, -5). We need to find the slope, equation of the line, and the y intercept of the line

First, let's find the slope

The formula for the slope (m) calculated from two points is \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 for the formula, but let's label the values of the points to avoid any confusion

x1=-1

y1=-3

x2=-2

y2=-5

Now substitute into the formula (remember: the formula has SUBTRACTION):

m=\frac{-5--3}{-2--1}

simplify

m=\frac{-5+3}{-2+1}

add

m=\frac{-2}{-1}

divide

m=2

So the slope is <u>2</u>

Now let's find the equation of the line

The question asks for it to be in slope-intercept form, which is y=mx+b, where m is the slope and b is the y intercept

We calculated the slope from earlier, so let's substitute that into the equation

y=2x+b

Now we need to find b

The equation will pass through both (-1, -3) and (-2, -5) so we can use either one of them to solve for b (doesn't matter which one)

Let's take (-1, -3) as an example

substitute -1 as x and -3 as y into the equation

-3=2(-1)+b

multiply

-3=-2+b

Add 2 to both sides

<u>-1=b (the value of the y intercept!) </u>

Substitute -1 as b into the equation

<u>y=2x-1</u>

We found everything needed for this problem

Hope this helps!
