Find y using Pythagorean theorem or proportion

Mathematics
1 answer:
Tcecarenko [31]2 years ago
4 0

We have three similar triangles, let's see if we can get this right, right vertex first, then other vertex from small side:

EDF ~ GDE ~ GEF

As ratios that means

ED:DF:EF = GD:DE:GE = GE:EF:GF

x:20:y = 5:x:GE = GE:y:15

Since we're after y we choose

20/y = y/15

20(15) = y²

y² = 300

y = 10√3

y ≈ 17.32

HELPPP!!!Kelsey uses the similarity statement to describe the triangles below.
Ganezh [65]

RT = 8 , RS = 3 AND ST = 5.4


RV = 4 , RU = 1.5 AND UV = 2.7


∴ RT/RV = 8/4 = 2


AND RS/RU = 3/1.5 = 2


AND ST/UV = 5.4/2.7 = 2


∴Δ RTS IS SIMILAR TO ΔRVU


SO, the best statement is:


Each pair of sides corresponds with a common ratio of 2.

The sum of two numbers is negative fifteen, and one number is five less than the other. Using the variables m and n to represent
Likurg_2 [28]

We need to use the variables m and n to represent both numbers.

Their sum must equal -15. Therefore, we can write the next equation:

m + n = -15

If one number is five less than the other, we need to choose one variable and then we can write it in terms of the other variable. Then:

n = m-5

To find the value for each number, we can replace the n equation on the first equation:

m + n = -15

m + (m-5)= -15

Then:

m + m - 5 = -15

2m -5 = -15

Solve the equation for m:

Add both sides 5 units:

2m - 5 +5 = -15+5

2m = -10

Divide both sides by 2:

2m/2 = -10/2

m = -5

Finally, replace the m value on the first equation:

m + n = -15

-5 + n = -15

Then, solve the equation for n:

Add both sides by 5:

-5+5 + n = -15 +5

n = -10

Hence, both numbers are m=-5 and n= -10.

The equations separated by a comma are m + n = -15,n = m-5.

The numbers separated by a comma are -5,-10.

Find the common ratio for 0.1,0.01,0.001
yulyashka [42]

The common ratio of the set of data is 0. 1

<h3>How to determine the common ratio</h3>

To determine the common ratio of a set of data, we have to

  • Divide the second term by the first term or
  • Divide the third term by the second term

For the given set of data

0.1,0.01,0.001

Let's divide the second term by the first term

= 0. 01/ 0. 1

= 0. 1

Thus, the common ratio of the set of data is 0. 1
