Answer:

\boxed{x = 7}

Step-by-step explanation:

ΔJKL ~ ΔMNP

So, the sides of both of the triangles are proportional.

Taking proportionality of their sides.

\frac{JL}{JK} = \frac{MP}{MN}

=> \frac{20}{25} = \frac{4x-4}{30}

Cross Multiplying

20 * 30 = 25(4x-4)

600 = 100x - 100

Adding 100 to both sides

600+100 = 120x

700 = 100x

Dividing both sides by 100

700/100 = x

x = 7

Given that point A is the midpoint of line segment ED, where E( -1,9) and A(4,5), what is the location of point D?
yuradex [85]

Answer:

  D(9, 1)

Step-by-step explanation:

A being the midpoint means its coordinates satisfy ...

  A = (E + D)/2

Solving for D, we find ...

  D = 2A -E

  = 2(4, 5) -(-1, 9) = (2·4 +1, 2·5 -9)

  D = (9, 1)

Answer:

The measure of the fourth angle = 137.1°

Step-by-step explanation:

Let x = the measure of the fourth angle

Sum of all 4 interior angles in a quadrilateral equal 360°

so

x + 23.5° + 99° + 100.4° = 360°

x + 222.9° = 360°

              x = 360° - 222.9°

              x = 137.1°

viva [34]
<h2>Answer:</h2><h2>If she  continues to throw darts 75 more times, she could predict to hit the </h2><h2>bull's-eye 15 times.</h2>

Step-by-step explanation:

Shay found that she hit the bull's-eye when throwing darts \frac{2}{10} times = \frac{1}{5}.

In five times, she will hit the dart once.

If she  continues to throw darts 75 more times,

the probability that she will hit the bull's eye =  \frac{1}{5} (75) = 15 times.

If she  continues to throw darts 75 more times, she could predict to hit the

bull's-eye 15 times.
