Answer:

:ABCD and 4|CD

(A.1000)+(B.100)+CD/4

ABCD and 4|CD

(A.1000)+(B.100)+CD/4

100(10.A+B)+CD/4

100(10.A+B)/4 + CD/4

Thus,

25(10.A+B) + CD/4, because 4|CD

Use the information to answer the questions.

Anna71 [15]

Answer:

Part 1) The length of two sides and the measure of the included angle (Side-Angle-Side)

Part 2) $b^2=a^2+c^2-2(a)(c)cos(B)$

Part 3) $b=11.6\ in$

Step-by-step explanation:

we have

In the triangle ABC

$a=11\ in\\c=9\ in\\B=70^o$

Part 1) Which information about the triangle is given?

In this problem we have the length of two sides and the measure of the included angle (Side-Angle-Side)

see the attached figure to better understand the problem

Part 2) Which formula can you use ti find b?

I can use the law of cosines

$b^2=a^2+c^2-2(a)(c)cos(B)$

we have

$a=11\ in\\c=9\ in\\B=70^o$

substitute the given values

$b^2=11^2+9^2-2(11)(9)cos(70^o)$

$b^2=202-67.72$

$b=11.59\ in$

Part 3) What is b, rounded to the nearest tenth?

Remember that

To Round a number

a) Decide which is the last digit to keep

b) Leave it the same if the next digit is less than $5$ (this is called rounding down)

c) But increase it by $1$ if the next digit is $5$ or more (this is called rounding up)

In this problem we have

$11.59\ in$

We want to keep the digit $5$

The next digit is $9$ which is 5 or more, so increase the "5" by 1 to "6"

therefore

$b=11.6\ in$

Since the value of b is 5, hence the equation of the horizontal line is x = 5

<h3>Equation of a line</h3>

A line is defined as the shortest distance between two points. The given line on the xy plane is a horizontal line.

The equation of a line is expressed as y = mx + b where;

m is the slope

b is the y -intercept

The equation of a horizontal line on the other hand is expressed as x = b

where b is the point where the horizontal line crosses the y-axis.

Since the value of b is 5, hence the equation of the horizontal line is x = 5
