Answer:

x = 10

Explanation:

Using Pythagoras Theorem:

  • a² + b² = c²

Solve:

8² + 6² = x²

x² = 64 + 36

x² = 100

x = √100

x = 10

<h3><u>Answer</u><u>:</u><u>-</u></h3>

10

<h3><u>Formula </u><u>used</u><u>:</u><u>-</u></h3>

Pythagoras theorem

(a² + b² = c²)

<h3><u>Explanation</u><u>:</u><u>-</u></h3>

Let ,

a = 8

b = 6

c = x

Using Pythagoras theorem,

=> 8² + 6² = x²

=> x² = 64 + 36

=> x² = 100

=> x = √100

=> x = 10

Hence, the length of x is 10.

Helene is finding the sum (9 10i) (–8 11i). She rewrites the sum as (–8 11)i (9 10)i. Which statement explains the property of a
Andreyy89

She made the mistake of grouping unlike terms and factorizing.

Given that

Helene is finding the sum (9 + 10i) + (–8 + 11i).

She rewrites the sum as (–8 + 11)i + (9 + 10)i.

We have to determine

Which statement explains the property of addition that she made an error in using?

According to the question

The mistake she did is in the second term distributing.

(9+10i) is not equal to (9+10)i

Similarly (-8+11i) is not equal to (-8+11)i.

The correct method she should have done is given below;

Grouping real terms together and imaginary terms together and finding the sum is,

\rm =  (9 + 10i) + (-8 + 11i)\\\\= 9+10i-8+11i\\\\= (9-8) +(10i+11i)\\\\=1+21i

Hence, she made the mistake of grouping unlike terms and factorizing.

To find the standard error, divide the standard deviation by the square root of the sample size

standard deviation = 7.5
sample size = 25......sqrt 25 = 5

standard error = 7.5 / 5 = 1.5 <==

Find x❤❤<br><br> I Will mark brainliest who answer first
andre [41]

Value of x is 35°

Step-by-step explanation:

  • Step 1: Since the line segment is a perpendicular bisector, the angle formed is equal to 90° and two triangles are also formed.

Find x using the property of triangles that sum of angles of a triangle is 180°

⇒ x° + 55° + 90° = 180°

⇒ x° + 145° = 180°

∴ x = 180 - 145 = 35°
