Given:
In isosceles triangle ABC, consider AB=BC and the segment BD with D a point on AC is the median to the base AC.
Perimeter of ABC is 50m and the perimeter of ABD is 40m.
To find:
The length of BD.
Solution:
In isosceles triangle ABC the segment BD with D a point on AC is the median to the base AC.
[tex]AB=BC[/tex] ...(i)
[tex]AD=CD[/tex]
[tex]AC=2AD[/tex] ...(ii)
Perimeter of ABC is 50m.
[tex]AB+BC+AC=50[/tex]
[tex]AB+AB+2AD=50[/tex] [Using (i) and (ii)]
[tex]2AB+2AD=50[/tex]
[tex]2(AB+AD)=50[/tex]
Divide both sides by 2.
[tex]AB+AD=25[/tex] ...(iii)
Now, perimeter of ABD is 40m.
[tex]AB+AD+BD=40[/tex]
[tex]25+BD=40[/tex] [Using (iii)]
[tex]BD=40-25[/tex]
[tex]BD=15[/tex]
Therefore, the length of BD is 15m.

AD is the angle bisector of EAB. Solve for X
Answer:
A) 5.76
Step-by-step explanation:
By angle bisector property of a triangle, we have:
[tex] \frac{12}{10} = \frac{x}{4.8} \\ \\ \frac{12 \times 4.8}{10} = x \\ \\ x = \frac{57.6}{10} \\ \\ x = 5.76[/tex]

Answer:
Mean:29.25
Median:25
Mode:25
Outlier:69
Range:53
Step-by-step explanation:
mean: 18+69+22+27+32+25+16+25/8=29.25
median: put in order: 16+18+22+25+25+27+32+69
middle is 25+25/2 which is 25.
median:25.
Mode = 25.
Outlier = 69.
Range is 69-16=53
Hope this helps :) pass your test :)
Answer:
mean = 29.25
median = 25
mode = 25
outlier = 69
range = 53
Step-by-step explanation:
Mean: add all values and divide by number of values 234 ÷ 8
Median: middle value if there are an odd number of data values, or the average of the two middle values if there are an even number of data values
Mode: data item seen most often
Outlier = data value that is extreme
Range = Highest value minus lowest value

Step-by-step explanation:
S is equal to Q
Q= 48.5
there are two angels (S,Q). They equal 48.5
so 48.5x2= 97
all angels together (QRSP) equals 360
you can take the 97 and subtract it from the 360 =263
divide 263 to get the angels for P and R
S= 48.5
Q=48.5
R=131.5
P=131.5
