Which statements are true about ΔJKL and ΔLMN? Select all that apply.

svp [43]

Answer:

A. ΔJKL and ΔLMN have only one pair of angles that are congruent

C. ΔJKL has angles that measure $50^o,60^o,70^o$

Step-by-step explanation:

step 1

Find the value of x

we know that

$m\angle KLJ=m\angle MLN$ ----> by vertical angles

substitute the given values

$(6x-2)^o=(5x+10)^o$

solve for x

$6x-5x=10+2\\x=12$

step 2

Find the measure of the interior angles of triangle JKL

we have

$m\angle KLJ=(6(12)-2)=70^o$

$m\angle KJL=(5(12))=60^o$

Remember that the sum of the interior angles in any triangle must be equal to 180 degrees

so

$m\angle JKL=180^o-130^o=50^o$

therefore

Triangle JKL has angles that measure $50^o,60^o,70^o$

step 3

Find the measure of the interior angles of triangle LMN

we have

$m\angle MLN=(5(12)+10)=70^o$

$m\angle LMN=(6(12)-7)=65^o$

Remember that the sum of the interior angles in any triangle must be equal to 180 degrees

so

$m\angle LNM=180^o-135^o=45^o$

Triangle LMN has angles that measure $45^o,65^o,70^o$

we know that

If two triangles are similar, then the ratio of its corresponding sides is proportional and its corresponding angles are congruent

The corresponding angles of triangle JKL and LMN are not congruent

therefore

The triangles are not similar

Verify each statement

Part a) ΔJKL and ΔLMN have only one pair of angles that are congruent

The statement is true (see the explanation)

Part b) ΔJKL and ΔLMN have two pairs of angles that are congruent

The statement is false

Because have only one pair of angles that are congruent

Part c) ΔJKL has angles that measure $50^o,60^o,70^o$

The statement is true (see the explanation)

Part d) ΔLMN has angles that measure $50^o,60^o,70^o$

The statement is false

Because, Triangle LMN has angles that measure $45^o,65^o,70^o$

Part e) ΔJKL and ΔLMN are similar

The statement is false

Because, the corresponding angles are not congruent

The number of lawns the workers in Angelo’s company have mowed in the first 6 weeks of the summer is 31, 24, 32, 28, 29, and 36.

Answer: MAD= 3

Step-by-step explanation:

Find the mean of the data set

31+24+32+28+29+36/6= 30

subtract EACH data by the mean, find the absolute value of the answer

31-30= 1 (absolute value)

24-30= 6 (absolute value)

32-30= 2 (absolute value)

28-30= 2 (absolute value)

29-30= 1 (absolute value)

36-30= 6 (absolute value)

Now find the mean of the values

1+6+2+2+1+6/6=3

MAD=3

Describe the location of the sum, relative to p, on a number line P+(-2)

il63 [147K]

Answer:

The location of the sum is 2 units before P (left to P)

Step-by-step explanation:

* Lets describe the number line

- A number line is a horizontal straight line with numbers placed at

an equal units

- A number line can be extended infinitely to the left and to the right

- A number line represents both positive and negative integers

- The numbers come on it from left to right

- The negative numbers come on the left of zero and the positive

numbers come on the right of zero

- Ex: -5 , -4 , -3 , -2 , -1 , 0 , 1 , 2 , 3 , 4 , 5 part of the numbers on the

number line

- To add numbers on the number line we start from first number of

the addition and if this number is added by a positive number we

go to right , if the number is added by a negative number

we go to left

- Ex: 5 + 3 ⇒ go from 5 to the right 3 units, then your position is at 8

2 + (-3) ⇒ go from 2 to the left 3 units then your position is at -1

* Now lets solve the problem

- The sum of P + (-2)

∵ Your location is P

∵ You will add P by (-2)

- Negative number means you go to the left

∴ Your position will be before P by two units

∴ The location of the sum is 2 units before P (left to P)
