Because the angles of both triangles are equal, they are similar triangles, and because they share side JL, they are congruent triangles. due to this, the length of side KJ=JM, therefore 2x-7=3x-16. solving this for x, we get that x=9. And because KJ=2x-7, plugging in 9 for x we get that KJ=11 m

Find all the square roots of x^2 ≡ 53 (mod 77) by hand. This is my second post. Please explain all the steps how you did this?

sasho [114]

Answer:

Step-by-step explanation:

Given that

$x^2 ≡ 53 (mod 77)$

Right side has values as

53, 53+77, 53+2(77),+....

We have to find one which is a perfect square.

We have from this series 361 is 19 square

Thus $x =19.$

Next is $x^2=900\\x=30$

$x^2=2209\\x=47$ and so on.

The width of a rectangle is the length minus 7 units. The area of the

AleksandrR [38]

Answer:

8 units

Step-by-step explanation:

here's your solution

=> let the length of rectangle be X

=> then width = x - 7

=> area = 8units

=>> area = length*width

=> area = x (x-7) = 8

=> x^2 - 7 = 8

=> now, x^2 - 7x - 8 = 0

=> factories the above equation by middle term split

=> x^2 - 7x - 8

=> x^2 - 8x + x - 8

=> take the common

=> x(x - 8) + 1(x - 8)

=> (x + 1) (x - 8)

neglect (x + 1) because this will in negative for X

=> x - 8 = 0

=> x = 8

=>so, x = 8

=>length = 8 units

Quadrilateral abcd is inscribed in a circle with m∠a = (x)degrees, m∠b = (2x - 10)degrees, and m∠c = (3x)degree. what is m∠d?

Lynna [10]

Hello,

When you have a polygon inscribed in a circle, the opposite angles are supplementary.

So we can start by saying that A + C = 180. Or x + 3x = 180. This gives us a value of 45 for x.

If we input that in for angle B, we get: 2(25) - 10 = 80.

If angle B = 80, then angle D must be 100, because the angles are supplementary.

Good luck,

At the kansas city airport, a group of pilots for skyways and yellow jet airlines were asked whether their flights were flying e

DiKsa [7]

The joint frequency that has the most flights is the Yellow Jet, going east. Option C. This is further explained below.

<h3>What is Frequency?</h3>

Generally, the occurrence per period with which something happens throughout a certain time period or in a given sample.

In conclusion, a beast with entries 30, 65, 65. the third column is labeled west with entries 33, 34, 67. the fourth column is labeled total with entries 63, 69, 132. Hence the Yellow Jet, going east. has the most flight.
