Option (6). HL

Step-by-step explanation:

Given:

From the right triangles ΔBAC and ΔBDC,

AC ≅ CD

∠A = ∠D = 90°

To Prove:

ΔBAC ≅ ΔBDC

            Statements                       Reasons

1). AC ≅ DC                        1). Given

2). BC ≅ BC                       2). Reflexive property

3). ΔABC ≅ ΔBDC            3). By HL property of congruence of right triangles

Therefore, Option (6) HL will be the correct option.                              

7x - 4 + x = -1 + 13x + 7
Show work

Answers

Answer:

7x-4+x=-1+13x+7

8x-4=13x+6

add 4 to both sides

8x-4+4=13x+6+4

8x=13x+10

subtract 13x from both sides

8x-13x=13x+10-13x

-5x=10

divide both sides by -5

-5x÷-5=10÷-5

x=-2

If these numbers represent elevations in meters, which is the farthest away from sea level?

Answers

Answer:

Option (1)

Step-by-step explanation:

Minus notation of the elevations from the sea level represents the distance below the sea level and positive notation represents the elevations above the sea level.

+7 → 7 meters above the sea level

-3 → 3 meters below the sea level

[tex]+\frac{1}{2}[/tex] → 0.5 meters above the sea level

-0.8 → 0.8 meters below the sea level

+0.8 → 0.8 meters above the sea level

[tex]-\frac{1}{10}[/tex] → 0.1 meters below the sea level

-2 → 2 meters below the sea level

Therefore, +7 meters above the sea level will be the farthest point from the sea level.

Jerry purchases a used sofa for $275. He cleans and reupholsters the sofa to make it look brand new. After all the improvements, Jerry sells the sofa for 40% more than what he originally purchased it for. What was the profit Jerry made after selling the sofa?

Answers

Answer:

$110

Step-by-step explanation:

Step one:

we are told that  the cost of the sofa is $275

also, he sells it for 40% more of the cost price

let us find 40% of $275

=40/100*275

=0.4*275

=110

=$110

Step two:

This means that the selling price is 275+110

=$385

profit = selling price- cost price

profit=385-275

profit=$110

What is the value of M ?

Answers

Answer:

m = 124 degrees.

Step-by-step explanation:

The sum of the interior angles of a triangle is 180.

The angle opposite m + 56 + 68 = 180.

The angle opposite m = 56.

The angle opposite m + m = 180, so 56 + m = 180.

Angle m = 124.

Simplify the following expression. (19x + 4y) + (49x + 32y)

Answers

Answer: 68x + 36y

Step-by-step explanation:

Combine Like Terms:

= 19x + 4y + 49x + 32y

= (19x + 49x) + (4y + 32y)

= 68x + 36y

Hope this helped you!

Answer:

68x + 36y

Step-by-step explanation:

You can compeletely get rid of the parenthesis because it is addition through and thorough.

You have 19x + 4y + 49x + 32y

You can combine like terms to get

19x +49x which is 68x

and

4y + 32y which is 36y

You now have 68 + 36y which cannot be simplified anymore because the variables are different.

Find the length of the shorter leg of a right triangle if the longer leg is 15 feet more than the shorter leg and the hypotenuse is 15 feet less than twice the shorter leg

Answers

Answer:

45

Step-by-step explanation:

Let the length of the shorter leg be represented as x.

Let the length of the longer let let be represented as x+15

While the length of the hypotenuse be 2x-15.

From the knowledge of phythagoras theorem:

x^2+(x+15)^2 = (2x-15)^2

x^2+x^2+15x+15x+225 = 4x^2-30x-30x+225

2x^2+30x+225 = 4x^2-60x+225

2x^2-4x^2+30x+60x+225-225=0

-2x^2+90x+0= 0

2x^2-90x = 0

Divide through by 2

x^2-45x=0

x(x-45)=0

x = 0 or x-45=0

Considering x-45=0

x-45=0

x = 45

If x is for the shorter leg,

The length for the longer leg is: x+15

= 45+15

= 60

For the hypotenuse = 2x-15

= 2×45-15

= 90-15

= 75

how do you find the measurement of an angle

Answers

You measure the size of an angle with a protractor. Or could be shown by an arc on the figure to indicate which angles that are congruent. Two angles whose measures together are 180° are called supplementary e.g. two right angles are supplementary since 90° + 90° = 180°.
