Answer:
[tex] x = 4 \sqrt{3} [/tex]
Step-by-step explanation:
By Pythagoras Theorem:
[tex] {x}^{2} = {( \sqrt{8 \times 4}) }^{2} + {(4)}^{2} \\ \\ {x}^{2} = {( \sqrt{32}) }^{2} + {(4)}^{2} \\ \\ {x}^{2} = 32 + 16 \\ \\ {x}^{2} = 48 \\ \\ x = \sqrt{48} \\ \\ x = \sqrt{ {4}^{2} \times 3} \\ \\ x = 4 \sqrt{3} [/tex]
Line BD is tangent to a circle with diameter AB. Explain why the measure of angle BCA must equal the measure of angle ABD.
Answer:
This is because angles inscribed in a semicircles are 90 degrees (BCA)
The tanget of that circle is also a 90 degree angle to the diameter (ABD)
Therefore they're both 90 degrees
The measure of angle BCA must equal the measure of angle ABD should be that angle should be inscribed in a semicircles that are 90 degrees,
What is the inscribed angle?In terms of geometry, an inscribed angle refer to the angle that should be created in the interior of a circle at the time when two chords should be intersect on the circle. It can also be refer to the angle subtended at a point on the circle via two given points on the circle.
Also, angle should be inscribed in a semicircles that are 90 degrees,

PLEASE HELPP
Answer:
x = 36°
Step-by-step explanation:
There are 180° on a line so 180° - 126° = 54°
54° is one of the angles and so is 90° (because it is a right angle)
Therefore, now we know that x = 180° - (54° + 90°)
54° + 90° = 144°
180° - 144° = 36°
x = 36°
Answer:
x = 36
Step-by-step explanation:
solution:
we have given,
in the right angled triangle.
exterior angle = [tex]126^{o}[/tex]
we know,
exterior angle = sum of interior non adjacent angle
so, [tex]126^o[/tex] = [tex]x + 90^o[/tex] [∵ one angle of right angled triangle is [tex]90^o[/tex]]
or, [tex]x = 126^o - 90^o\\[/tex]
or, [tex]x = 36^o[/tex]
hence, the value of x is [tex]36^o[/tex]

What is the mode, mean, median for these numbers?
{18,18,63,63,84}
Answer:
Mean= the average of the number set= 18+18+63+63+84=246/5=49.2
Median- the number in the middle of the set= 63
Mode- the number(s) that repeat=1 8, 63
Range- the amount between the highest and lowest numbers= 84-18=66
Step-by-step explanation:
The mode, mean, and median of the data will be 18 or 63, 49.2, and 63, respectively.
What are statistics?Statistics is the study of collection, analysis, interpretation, and presentation of data or discipline to collect and summarise the data.
The data set is given below.
18, 18, 63, 63, 84
The mode of the data is given as,
Mode = Frequency of the repeated number
Mode = 18 and 63
The mean of the data is given as,
Mean = (Sum of observations) / (Number of observations)
Mean = (18 + 18 + 63 + 63 + 84) / 5
Mean = 246 / 5
Mean = 49.2
The median of the data is given as,
Median = (n + 1)th / 2
Median = (5 + 1)th / 2
Median = 6th / 2
Median = 3th
Median = 63
The mode, mean, and median of the data will be 18 or 63, 49.2, and 63, respectively.

Line j passes through points (9, 6) and (6, 8). Line k passes through points (7, 9) and (5, 6). Are line j and line k parallel or perpendicular?
9514 1404 393
Answer:
perpendicular
Step-by-step explanation:
A graph shows the lines are not parallel. The lines are perpendicular.
__
j has a slope of -2/3 (down 2 for each 3 to the right)
k has a slope of 3/2 (up 3 for each 2 to the right)
These slope values have a product of 1, typical of perpendicular lines.

Help ASAP I’ll mark you as brainlister
Answer:
76 units
Step-by-step explanation:
In the given figure, a circle with center Q is inscribed in triangle AHD.
Let the circle with center Q touches the side HD at point N.
So, AT & AM, DM & DN and HT & HN are tangents drawn from external points A, D and H respectively.
Since, measure of tangsnts drawn from external point to a circle are equal.
Therefore,
AM = AT = 18
HN = HT = 8
DM = DN = 12
AH = AT + HT = 18 + 8 = 26
AD = AM + DM = 18 + 12 = 30
HD = DN + HN = 12 + 8 = 20
Perimeter of triangle
= AH + AD + HD
= 26 + 30 + 20
= 76 units
-6 + x = 4x pls help !
Answer:
Step-by-step explanation:
Alright so we are going to be simplifying here
-6 + x = 4x Flip sides
x-6=4x
After that,
x-6=4x Subtract 4x from both sides
-3x-6=0
Step 3
-3x-6=0 Add 6 to the sides
-3x=6
Step 4
-3x=6 Divide the sides by 3
-2
So therefore,
Your answer would be x=-2
