Answer 1

Given that

In ∆ ABD , AB = BD------(1)

=> Angle B = Angle D

Since the angles opposite to equal sides are equal.

=> Angle A = Angle D

and

BC bisects Angle B

=> Angle BCA = Angle CDB ----(2)

And

BC = BC (Reflexive Property) -----(3)

From Eqⁿ(1),(2)&(3) we have

BA = BD

< ABC = BCD

BC = BC ( Common Side)

Therefore, ∆ ABC =~ ∆ DBC

by SAS property

Hence, proved.

Additional comment:

The angles opposite to equal sides are equal.In two triangles , the two sides and the included angle of the first triangle are equal to the corresponding two sides and the included angle in the second triangle then they are congruent and this property is called Side-Angle-Side (SAS) Property.CPCT - Corresponding parts in the Congruent triangles are equal.Angle bisector divides the angle into two equal parts.The sum of two adajacent angles is 180° they are called Linear Pair.

ANGLES OF A TRIANGLE SOMEONE ANSWER ASAP PLS ! );

Answers

Answer:

∠K = 123°

∠L = 97°

∠O = 83°

∠N = 40°

Step-by-step explanation:

∠K and ∡57° are Supplementary, so their sum is equal to 180°

180 - 57 = 123

∠K = 123°

∠N and ∡140° are also Supplementary

180 - 140 = 40

∠N = 40°

The area of a triangle is equal to 180 when all angles are added together

40 + 57 = 97

180 - 97 = 83

∠O = 83°

∠L is an outside angle, which is equal to the sum of the 2 further angles (in this case ∡57° and ∠N) which we found was 97° when solving for ∠O

∠L = 97°

Now to check ∠K we add ∠O and ∠N

83 + 40 = 123

Now we also check ∠O with ∡140°

140 - 57 = 83

So all of the angles check out correctly

Step-by-step explanation:

Given,To find the value of k

Equation:-2k - 4k = -18

Solution:

=> -2k - 4k = -18

(On adding like terms -2k and -4k)

Kendra saw a calculator on sale for $68.25. The original price of the calculator was $89.99.

What is the approximate discount on the calculator?


20%

25%

30%

35%

Answers

The approximate percentage discount is equal to 25%.

Given the following data:

Sales price = $68.25.Original price = 89.99

To calculate the approximate discount on the calculator:

First of all, we would determine the discount on the calculator by using the following mathematical expression:

[tex]Discount = Original\;price -Sales\;price[/tex]

[tex]Discount = 89.99 -68.25[/tex]

Discount = $21.74

Now, we can calculate the approximate percentage discount:

[tex]Percent\;discount = \frac{21.74}{89.99} \times 100\\\\Percent\;discount = \frac{2174}{89.99}\\\\Percent\;discount = 24.16[/tex]

Percent discount = 25%

A. $2.63
B. $28.95
C.$41.63
D. $45.75

Answers

the correct answer is C

The total cost of the video controller is $41.63.

The correct option is C.

What is a percentage?

A ratio or value that may be stated as a fraction of 100 is called a percentage. And it is represented by the symbol '%'.

Given:

A video controller cost $39.

If a 6.75% sales tax is added,

that means,

6.75% of 39,

= 6.75 x 39 / 100

= 2.6325 taxed amount.

The total cost = 39 + 2.6325 = 41.63.

Therefore, $41.63 is the total cost.

share 5,000 in the ratio of 1:2:3:4​

Answers

Answer:

500 : 1000 : 1500 : 2000

Step-by-step explanation:

sum the parts of the ratio , 1 + 2 + 3 + 4 = 10 parts

Divide the amount by 10 to find the value of one part of the ratio

5000 ÷ 10 = 500 ← value of 1 part of the ratio , then

2 parts = 2 × 500 = 1000

3 parts = 3 × 500 = 1500

4 parts = 4 × 500 = 2000

5000 = 500 : 1000 : 1500 : 2000 in the ratio 1 : 2 : 3 : 4

Total
1:2:3:4 10
500:1000:1500:2000 5000

Steps:

1+2+3+4=10
5000 divided by 10= 500
500x1=500
500x2=1000
500x3=1500
500x4=2000

So the final answer is

500:1000:1500:2000
