In order for the parallelogram to be a rhombus x=

Mathematics
1 answer:
Eva8 [605]2 years ago
4 0

Answer:

17

Step-by-step explanation:

Properties used:-

All sides of rhombus are equal therefore in the triangles

EQUAL SIDE OPPOSITE TO ANGLES, ANGLES BECOME EQUAL

then we use alternate interior angles

Then we get,

3x-11=x+23

2x=34

x=17

What is the value of the sum of all the terms of the geometric series 300, 60, 12, …?
ruslelena [56]
<h3>Answer:   375</h3>

=========================================

Work Shown:

a = 300 = first term

r = 60/300 = 0.2 = common ratio

We multiply each term by 0.2, aka 1/5, to get the next term.

Since -1 < r < 1 is true, we can use the infinite geometric sum formula below

S = a/(1-r)

S = 300/(1-0.2)

S = 300/0.8

S = 375

----------

As a sort of "check", we can add up partial sums like so

  • 300+60 = 360
  • 300+60+12 = 360+12 = 372
  • 300+60+12+2.4 = 372+2.4 = 374.4
  • 300+60+12+2.4+0.48 = 374.4+0.48 = 374.88

and so on. The idea is that each time we add on a new term, we should be getting closer and closer to 375. I put "check" in quotation marks because it's probably not the rigorous of checks possible. But it may give a good idea of what's going on.

----------

Side note: If the common ratio r was either r < -1 or r > 1, then the terms we add on would get larger and larger. This would mean we don't approach a single finite value with the infinite sum.

Please solve for X and show step by step equation
larisa [96]

Answer:

6

Step-by-step explanation:

Firstly, this is the pythagoreans theorem a^2+b^2=c^2

Now that we know that, we will solve for x.

(x+2)^2+x^2=100 ( The 100 is just 10 squared )

Finally, you solve for x and get 6.

Can u guys help me with these two problems?? for the first one I got 76 ,but I don't think is right.
Elina [12.6K]

Answer:

See below

Step-by-step explanation:

15)

In the right-angle triangle, once one of the angles is 44º, then, the unknown angle is x.

180 = 44 + 90 + x

180 = 134 + x

x= 46

The angle y of the other triangle plus the angle x of the right-angle triangle is equal to 90º, therefore they are complementary angles.

So,

90 = x + y

90 = 46 + y

y=44

To find ?, we have

180 = 58 + 44 +?

180 = 58 + 44 +?

? =78

16)

The sum of the internal angles of the triangle with angles 50º and 25º is equal to 180º, therefore, the other angle is

180 = x + 50 + 25\\180 = x+ 75\\x=105

Once the angles are opposite, they are the same. For the triangle with the 36º angle, we have

180 = 36 + 105 + y

180 = 141+ y

y=39

?=39
