ΔLMN ≅ ΔLQP by (SAA)

Step-by-step explanation:

It is given that line (NM) is congruent to the line (PQ), meaning they have the same measure. This is signified by the small red line on each of these sides.

Moreover, it is also given that angle (MNL) is congruent to angle (QPL), this is shown by the red arc around these angles.

Finally one can figure out that angle (NLM) is congruent to angle (PLQ) by the vertical angles theorem. The verticle angles theorem states that when two lines intersect, the opposite angles are congruent.

Thus the two triangles are congruent by side-angle-angle postulate, abbreviated as (SAA).

Explicação passo a passo:

Dado que :

Taxa de conversão = 65%

Número de fotos tiradas = 20

O número estimado de gols marcados será:

O produto da taxa de conversão e o número de fotos tiradas;

Número de fotos tiradas * taxa de conversão

20 * 65%

20 * 0,65

Answer:

x = 70°, y = 110° , z = 85°

Step-by-step explanation:

∠ BEA and ∠ CDA are corresponding angles and congruent , then

x = 70°

x and y are adjacent angles and sum to 180°

x + y = 180°

70° + y = 180° ( subtract 70° from both sides )

y = 110°

∠ ABE and ∠ ACD are corresponding angles and congruent , then

Justin has a savings account.
• He started with $70 in his account.
• He deposits $15 into the account each week.
What is the total amount Justin will have in his account after 10 weeks?

Answers

Answer:

220

Step-by-step explanation:

Multiply 15 times 10 =150

150+70=220

Hope this helps :)

Answer:  220 dollars

==========================================================

Explanation:

After 10 weeks, he'll deposit a total of 15*10 = 150 dollars on top of the $70 already in the account. This means the grand total is 150+70 = 220 dollars

If you need to use algebra, then an algebraic expression you can use is 70+15x where x is the number of weeks. Replace x with 10 and you'll end up with 70+15*10 = 70+150 = 220. It's effectively the same idea and steps as the previous paragraph, but now we're involving a variable.

15 similar blouses and 2 similar skirts cost $505. 5 such blouses and 2 such
skirts cost $215. How much do 5 such blouses cost? need this ans asap!​

Answers

Answer:

Cost of five blouses = $145

Step-by-step explanation:

Let

x = cost of blouse

y = cost of skirt

15x + 2y = 505 (1)

5x + 2y = 215 (2)

Subtract (2) from (1) to eliminate y

15x - 5x = 505 - 215

10x = 290

x = 290/10

x = 29

Substitute x = 29 into (2)

5x + 2y = 215 (2)

5(29) + 2y = 215

145 + 2y = 215

2y = 215 - 145

2y = 70

y = 70/2

y = 35

x = cost of blouse = $29

y = cost of skirt = $35

How much do 5 such blouses cost?

cost of a blouse = $29

Cost of five blouses = $29 × 5

= $145

Cost of five blouses = $145

Answers

Complete question :

A city has a higher elevation than Coachella, CA.

Coachella's elevation is 22 feet below sea level (-22 ft.)

Select the four numbers that could represent the city’s elevation. Be prepared to explain your reasoning.

-11 feet

4 feet

-8 feet

-35 feet

0 feet

-44 feet

Answer:

- 11 feets

4 feets

0 feets

-8 feets

Step-by-step explanation:

Kindly note, that, elevation below sea level should be represented with negative Integers:

Coachella's elevation = - 22 feets

SINCE it is a stated that city A has a higher elevation than Coachella ;

Therefore, Elevation of city A is greater than - 22 feets

Therefore x from the options possible elevation of city A are :

All values in the option greater than - 22; The numbers include :

-8 feets, 0 feets, - 11 fees, 4 feets

is 15m 36m 39m right triangle

Answers

Answer is below. Look at my explanation to understand my answer.

To see if these lengths can make a triangle, we can use the "triangle side theorem."

The formula is:

a + b > c

a + c > b

b + c > a

So, with that being said...

15 → A

36 → B

39 → C

So, we can use the triangle side theorem by adding A & B, A & C, and B & C.

If the side length is greater than C, B, or A, it can make a triangle. But if it isn't greater than C, B, or A, it cannot make a triangle.

So, let's add 15 and 36 to see if it can make a triangle.

15 + 36 = 51

If you read above, C is 39.

So, 51 > 39

15 + 36 > 39 ✓

Let's repeat this process again.

Instead of C, B is what we're now seeing if the sum is greater than it.

15 + 39 = 54

54 is greater than 36...

54 > 36

So it is true.

15 + 39 > 36 ✓

Now, A is what we're seeing if the sum is greater than it.

36 + 39 = 75

75 is greater than 15...

75 > 15

So it is true.

36 + 39 > 15 ✓

So yes, these lengths can make a triangle.

Let me know of any questions or concerns.

given a is equal to 60 degree and 30 degree prove that sin a + b is equal to sin a cos b + cos a sin b ​

Answers

Answer:

A = 60 and B = 30  

Now, A + B = 60 + 30 = 90  

Also, A – B = 60 – 30 = 30  

sin (A + B) = sin 90 = 1  

sin A cos B + cos A sin B = sin 60 cos 30 + cos 60 sin 30

1) Find the value of x. Round to the nearest tenth.

Answers

Answer:

x ≈ 12.9

Step-by-step explanation:

Using the tangent ratio in the right triangle

tan35° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{9}{x}[/tex] ( multiply both sides by x )

x × tan35° = 9 ( divide both sides by tan35° )

x = [tex]\frac{9}{tan35}[/tex] ≈ 12.9 ( to the nearest tenth )

Ok...so we have this........

y = ax2 + 4      ....... and we need to find "a"

So we have

-1 = a(-10)2 + 4

-5 = a (100)

(-1/20) = a      .......  So we have ..........

y = (-1/20)(x- 0)2 + 4   or just  (-1/20)x2 + 4

Note that this parabola opens downward...That makes sense since the vertex is above the x axis and the parabola passes through a point below the x axis.
