Step-by-step explanation:

Since the two triangles are congruent this means that corresponding angles are congruent so

Angle X= Angle M

Angle Y equal Angle N

Angle Z equal Angle L.

That means that Angle M is 33 degrees.

Angle Y is 124 degrees.

We can find Angle Z by doing triangle interior theorem.

$124 + 33 + x = 180$

$157 + x = 180$

$x = 23$

So Angle Z equal 23.

Congruent triangles also have corresponding sides that are equal so that means

XY=MN

YZ=NL

XZ= ML

So that means XY=8

I just need one more answer to this. Please someone help!

Answer:

(1,0)

(-2,3)

(5,24)

Step-by-step explanation:

To solve this you can can just plug in the x and y values and see which work

y = x²-1

Lets test (0,1):

1 = 0²-1

1 = -1

This pair does not work, because 1 does not equal -1

Lets test (1,0):

0 = 1²-1

0 = 0

This does work, because 0 equals 0

Lets test (3,5):

5 = 3²-1

5 = 9 - 1

5 = 8

This pair does not work, because 5 does not equal 8

Lets test (5,24):

24 = 5²-1

24 = 25 -1

24 = 24

This pair does work, because 24 equals 24

Lets test (-2,3):

3 = (-2)²-1

3 = 4-1

3 = 3

This pair does work, because 3 equals 3

Lets test (-4,-17):

-17 = (-4)²-1

-17 = 16 - 1

-17 = 15

This pair does not work, because -17 does not equal 15

So the pairs that are on the graph are:

(1,0)

(-2,3)

(5,24)

Thaddeus wants to cover an area around a pond with natural slate stone. If the cost of the slate is $6.50 per square foot, how m

igomit [66]

Answer:

Cost of slate path using π: $980.18 (nearest cent)

Cost of slate path using π = 3.14: $979.68

Step-by-step explanation:

Formula

Area of a circle = πr² (where r is the radius)

First, calculate the area of the slate path by subtracting the area of the pond from the area of the larger circle.

Area of larger circle = π · 8² = 64π ft²

Area of pond (smaller circle) = π · 4² = 16π ft²

⇒ area of slate path = 64π - 16π = 48π ft²

If the cost of the slate is $6.50 per ft² then,

Cost of slate path using π:

⇒ 48π × $6.50 = $980.18 (nearest cent)

Cost of slate path using π = 3.14:

⇒ 48 × 3.14 × $6.50 = $979.68

the number m and 5/8 are additive inverses.drag and drop m to their correct positions on the number line.drag and drop the label

monitta

The additive inverse of a number is that number with its sign changed.

The additive inverse of 5/8 is -5/8, so that is the value of m.

The sum of a number and its additive inverse is zero. (This is actually the definition of additive inverse.)

5/8 is found at 5/8 on the number line.

m is found at -5/8 on the number line.

"sum" is found at 0 on the number line.

Find the length of LM. Show your work.

Fantom [35]

Answer:

LM = 20

Step-by-step explanation:

Use the Sine rule to calculate the length of LM

We require to find ∠N using sum of angles in a triangle.

∠N = 180° - (53 + 44)° = 180° - 97° = 83°, then

$\frac{LN}{sin44}$ = $\frac{LM}{sin83}$ ( cross- m ultiply )

LM × sin44° = LN × sin83°, that is

LM × sin44° = 14 × sin83° ( divide both sides by sin44° )

LM = $\frac{14sin83}{sin44}$ = 20
