Given that ABCD is a rhombus, find the value of x. (X+14)

Mathematics
1 answer:
Kay [80]3 years ago
6 0

Answer:

option B. x=38^o

Step-by-step explanation:

we know that

1) The two diagonals of a rhombus are perpendicular

2) The sum of the interior angles in any triangle must be equal to 180 degrees

Let

O ----> the intersection point of the diagonals of the rhombus

In the right triangle OAD

x^o+(x+14)^o+90^o=180^o

solve for x

x^o+(x+14)^o=90^o

2x=90^o-14^o

2x=76^o

x=38^o

Which value is equivalent to<br> 3/11?<br> OA A. 0.27<br> O<br> B. 0.27<br> OC<br> C. 3.6<br> OD. 3.
Sladkaya [172]

Answer:

0.27 repeating.

Step-by-step explanation:

So to solve this we just have to use division.

1 clearly doesnt go into 3 at least one time, so we can add a decimal point and add a 0 to make it 30.

11 goes into 30 2 times, so we have:

0.2

and 30-22=8

So we can add another 0 and make it 80.

Then 11 goes into 80 7 times. So we have:

0.27

and 80-77=3

So again, add the 0, we have 30.

11 goes into 30 2 times, so:

0.272

and 30-22=8

Add another 0 we get 80.

11 goes into 80 7 times.

So finally, we have:

0.2727.

This is a repeating decimal.

This can be shown as:

0.<u>27</u>

So this is your answer!

I was a bit confused with which one it was on your answer key, but knowing that it is 0.<u>27</u> I am guessing you can chose!

Hope this helps!

If you have five red balls and five blue balls in a jar what’s the probability of the first ball being red?
rosijanka [135]

Answer:

red balls = 5

blue balls = 5

total balls = 5 blue+5 red

= 10

p(first \: ball \: being \: red) =  \frac{red \: balls}{total \: balls}

p(first \: ball \: being \: red) =  \frac{5}{10}  =  \frac{1}{2}
