What is the solution to x?​

Mathematics
1 answer:
Sonja [21]3 years ago
3 0

Answer:

Step-by-step explanation:

By geometric mean theorem,

In a triangle ABC,

\frac{BC}{AC}=\frac{CD}{BC}

\frac{y}{(4+6)}=\frac{6}{y}

y² = 60

y = √60

y = 7.75

Similarly, \frac{AB}{AC}=\frac{AD}{AB}

\frac{x}{(4+6)}=\frac{4}{x}

x² = 40

x = √40

x = 6.32

Valentin [98]

Answer:

\sf \Bigg[ \frac{ ( - 4 \times ( - 3)) }{2} \Bigg] \: and  \: \Bigg[ \frac{ - ( - 5 \times 8)}{10} + 2 \Bigg]

Step-by-step explanation:

Given:

The \: numbers \rightarrow -4, 10, 8, 2, -3, -5

To find:

Two expressions that equal 6 using the given numbers

Solution:

Expression first,

Using numbers -4, 2, -3,

aligning the above numbers as,

\frac{ ( - 4 \times ( - 3))  }{2}

will out put 6.

<em>Verification,</em>

\frac{ ( - 4 \times ( - 3))  }{2} =  \frac{12}{2}   = \cancel\frac{12}{2} = 6

Expression second,

Using numbers 10,8,2,-5

aligning the above numbers as,

\frac{ - ( - 5 \times 8)}{10} + 2

will result 6.

<em>Verification</em>

\frac{ - ( - 5 \times 8)}{10} + 2 =  \frac{ 40}{10}  + 2   \\ \\ \frac{ - ( - 5 \times 8)}{10} + 2= 4 + 2 \\  \\\frac{ - ( - 5 \times 8)}{10} + 2  = 6

Answer:

Step-by-step explanation:

At the point where two line cut across, the vertically opposite angles formed are equal. This means that

2x degrees = 78 degrees

Dividing the left hand side and the right hand side of the equation by 2, it becomes

2x/2 = 78/2

x = 39

Checking,

The sum of the angles on a straight line is 180 degrees.

180 - 78 = 102 degrees

2x + 102 = 180

2x = 180 - 102 = 78

x = 78/2 = 39
