Answer:

(a) Side lengths

RS = \sqrt{5}     ST = \sqrt{17}    RT = \sqrt{18}

(b) Slope

RS = \frac{1}{2}      RT = 1      ST = -4

(c) Scalene triangle

Step-by-step explanation:

Given

R = (2,3)

S = (4,4)

T = (5,0)\\

Solving (a): Length of each side

This is calculated using distance formula

d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}

So, we have:

RS = \sqrt{(4 - 2)^2 + (4 - 3)^2}

RS = \sqrt{5}

ST = \sqrt{(5 - 4)^2 + (0- 4)^2}

ST = \sqrt{17}

RT = \sqrt{(5 - 2)^2 + (0 - 3)^2}

RT = \sqrt{18}

Solving (b): The slope of each side

This is calculated using:

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

So, we have:

RS = \frac{4- 3}{4- 2}

RS = \frac{1}{2}

RT = \frac{0 - 3}{5- 2}

RT = \frac{ - 3}{- 3}

RT = 1

ST = \frac{0 - 4}{5- 4}

ST = \frac{- 4}{1}

ST = -4

Solving (c): Classify the triangle

In (a), we have:

RS = \sqrt{5}

ST = \sqrt{17}

RT = \sqrt{18}

None of the sides are equal;

The triangle is scalene

Find mMK................
Gnesinka [82]

Answer:

Approximately mMK is 53 degrees

Step-by-step explanation:

Here, we want to find the length of MK

As we can see, we have a right triangle at LNK

so

let us find the angle at L first

9 is adjacent to the angle at L and also, 15 is the hypotenuse of the angle at L

so the trigonometric identity that connects adjacent to the hypotenuse is the cosine

It is the ratio of the adjacent to the hypotenuse

So;

cos L = 9/15

L = arc cos (9/15)

L = 53.13 degree

Approximately, L = 53 degrees

so now, we want to get the arc length MK

We are to use the angle-arc relationship here

Using this; arc length MK is equal to the measure of L at the center which is 53 degrees

</span><span>1/55

</span><span><u>Explanation</u>
</span><span>The probability of an event is a chance of it happening. It is calculated as;
Probability =(fouvarable outcome)/(total outcome)
Since we are finding the probability of no girl will be chosen, it is like finding the probability of choosing 3 boys.
The probability of choosing the first boy =4/12
The probability of choosing the second boy =3/11
The probability of choosing the third boy =2/10
The probability of choosing the 3 boys will be,
=4/12×3/11×2/10
=24/1320
=1/55

4. Find the value of x. The diagram is not to scale.
borishaifa [10]

Answer:

x = 47 degrees

Step-by-step explanation:

First, find the supplementary angle by subtracting 180 from 103, which you get  77 degrees.

Then, add 77 and 56 to get 133 degrees.

Subtract 180 from 133 and you get 47 degrees.
