9. Find the missing values for the following similar figures

Answers

Answer 1

The missing values of the similar triangles is x = 20/3 and y = 4.5

What are similar triangles?

If two triangles' corresponding angles are congruent and their corresponding sides are proportional, they are said to be similar triangles. In other words, similar triangles have the same shape but may or may not be the same size. The triangles are congruent if their corresponding sides are also of identical length.

Corresponding sides of similar triangles are in the same ratio. The ratio of area of similar triangles is the same as the ratio of the square of any pair of their corresponding sides

Given data ,

Let the first triangle be ΔABC

Let the second triangle be ΔXYZ

Now , the corresponding sides are

15 / 10 = y / 3

Multiply by 3 on both sides , we get

y = 45 / 10

y = 4.5

Now , for the similar triangles , corresponding sides of similar triangles are in the same ratio

And , 2 / 3 = x / 10

Multiply by 10 on both sides , we get

x = 20/3

Hence , the similar triangles are solved

Answer:

Step-by-step explanation:

First step is finding an angle in the rightmost triangle (angle K)

Using TOA we have

Tan(x)=4/8

x=26.565

which means that 90-26.565= 63.4349 will give us angle K in regards to the left triangle

Using this we can solve for JM

Tan(63.4349)=x/8

8tan(63.4349=x

x=16

So if JM = 16

and LM=4

take their sum to find JL

16+4=20

Mahmoud is working out the height, h metres, of a tower

BT which stands on level ground.

He measures the angle TAB as 25°.

He cannot measure the distance AB and so he walks 80 m

from A to C, where angle ACB = 18° and angle ABC = 90°.

Calculate

Answers

Answer:

24.72 m

11.53 m

Step-by-step explanation:

Horizontal distance AB can be obtained from △ABC

From trigonometry :

Sin18° = opposite / hypotenus

Sin18° = AB / 80

AB = 0.3090169 * 80

AB = 24.72 m

The height BT, of tower from △ABT

From trigonometry :

Tan25° = opposite / Adjacent

Tan25° = h / 24.72m

h = Tan25 * 24.72

h = 11.527

h = 11.53 m

Hence, height of tower BT = 11.53 m

Your friend has n pennies. You have 29 pennies. You and your friend have a total of 40 pennies. Which equation could be used to find n?

Answers

Answer:

40-29=n

Step-by-step explanation:

You have 29 in total yall have 40

so to find ur friends we subtract

Answer:

Step-by-step explanation:

your pennies + your friends pennies = the total number of pennies between you two

so the equation would be :

29 + n = 40

(im not sure if you wanted it solved for n but here is the solution just in case)

29 + n = 40

n = 40 - 29

n = 11

Answers

The answer is 15.01

First you need to find the other angle of the triangle so you do 90+25 which gives you 115 and subtract that by 180 because all angles of a triangle add up to 180. That gives you 65 then you will use TAN(65) and get 2.144506920509559 which you will then multiple by 7 to get 15.01154844356691 which you then round to get 15.01!

If the purchase price for a house is $309,900, what is the monthly payment if you put 20% down for a 30 year loan with a fixed rate of 6%? A. $729.98 b. $912.48 c. $1,486.41 d. $1,858.01 Please select the best answer from the choices provided A B C D

Answers

Answer:

The correct answer is A. $729.98.

Step-by-step explanation:

Given that the purchase price for a house is $ 309,900, to determine what is the monthly payment if you put 20% down for a 30 year loan with a fixed rate of 6%, the following calculation must be performed:

100 - 20 = 80

(309,900 x 0.80) x 1.06 / (30x12) = X

247,920 x 1.06 / 360 = X

262,795.2 / 360 = X

729.98 = X

Therefore, the monthly payments will be $ 729.98.

Answer:

Monthly Payment = 1,486.41
