Answer:

x = 80 degrees

Step-by-step explanation:

Draw a line through DG and name the intersection of that line and line AB as K.

By the same side interior angle theorem, GKC is 40 degrees.

By the sum of interior angles of triangle theorem, CGK is 180-70=110 degrees.

By supplementary angle theorem, x = 80 degrees.

Find the reflection of point (50, 25) across the x-axis.

serious [3.7K]

The reflection of any point across the x-axis:

⇒ means that x-coordinate remains the same

⇒ but the y-coordinate is multiplied by '-1'

In this case:

⇒ (50,25) becomes (50,-25)

Answer: (50,-25)

Hope that helps!

PolarNik [594]

Answer:

0.00397

Step-by-step explanation:

I am taking a guess. Like I saw this example (5/9)(4/8)(3/7)(2/6)=120/3024=0.0397

Or (5C4)/(9C4)=0.0397 - from chisnau

Follow those steps, but add your numbers . I added one zero bassed on the problem: There are 9 students in a class: 5 boys and 4 girls. If the teacher picks a group of 4 at random, what is the probability that everyone in the group is a boy?

Hope I helped in some way!

I need help.. but we are only doing question 34 please answer quickly

TEA [102]

Answer: 33. r=13.6 34. m=12

Step-by-step explanation:

33.

-0.8+r=12.8

-0.8+r+0.8=12.8+0.8

r=13.6

34.

$\displaystyle\\-\frac{m}{3}=-4\\\\\frac{m}{-3}=-4$

Multiply both parts of the equation by -3:

$\displaystyle\\\frac{m}{-3}(-3)=(-4)(-3)\\\\ \frac{m(-3)}{-3} =12\\\\m=12$

6. A square field has an area of 479 ft². What is the approximate length of a side of the field?

anastassius [24]

Answer:

22 Feet

Step-by-step explanation:

All the lengths of a square are the same length.

The area of a square is the length times the width. The length and the width are the same measurement. So, we are looking for the square root of 479.

$\sqrt{479}$

21.88606863 is as far as my calculator goes. This is an irrational number. That means that it never repeats or terminates as a decimal. They tell us to answer to the nearest foot. That would be 22 feet.
