Answer:
See below.
Step-by-step explanation:
By definition the median of the triangle bisects the base of the isosceles triangle.
We need to prove that the 2 triangles formed by the median are congruent.
If the 2 triangles are ABD and ACD where BD is the median and < ABC is the angle from which BD is drawn.
BD = BD ( the common side)
AD = DC ( because BD is the median).
AB = AC ( because ABC is an isosceles triangle).
So Triangles ABD and ACD are congruent by SSS.
Therefore m < ABD = m < CBD, so BD is the bisector of < ABC.
To prove BD is also the altitude:
Triangles ABD and CBD are congruent as we have just proven. Therefore the
of measure of the base angle ABD = m < CBD . Also they are adjacent angles ( on the same line) so they add up to 180.
Therefore angles ABD and CBD are both right angles and BD is the altitude of triangle ABC.
X=8.5
190-5=185
185/-5=-37
-37-3=-34
34/4=8.5
Answer:
- 13.077
Step-by-step explanation:
Here we have to calculate the square root of a certain number using the help of the calculator or a square root table.
The given expression is 
.
Now, using calculator 
Now, 
So, approximate value to the nearest thousandth is - 13.077 ( Answer )
Find how much is reamaining
remaining=1-used
used=tomatoes+beens
used=5/9+1/12
5/9 times 12/12=60/108
1/12 times 9/9=9/108
used=60/108+9/108
used=69/108
used=23/36
1-23/36=
36/36-23/36=
13/36
answer is 13/36
