Answer:
x = 3.6
Step-by-step explanation:
The angle bisector divides the triangle proportionally.
The base segment to the right of the bisector is 6-x, so we can write the proportion ...
x/6 = (6-x)/4
Multiplying by 12, we get ...
2x = 3(6 -x)
5x = 18 . . . . . add 3x
x = 18/5 . . . . divide by 5
x = 3.6
_____
<em>Alternate solution</em>
Since the base of the triangle is given as a left-part and a sum-of-both-parts, we can write the proportion the same way:
left-part / sum-of-both-parts = x/6 = 6/(6+4)
Then the solution is x = 6(6/10) = 36/10 = 3.6.
Doing it this way avoids having x on both sides of the equation, so makes solving the equation be "one step."
For congruence of triangles.
If;
Then the corresponding sides and angles will be equal.
Only the above congruence statements are true.
Any options that has any of the above congruence statement is true.
Answer:
2/3
Step-by-step explanation:
You have 6 friends who want to share 4 brownies equally. You simply divide the 4 brownies by 6 people:
4/6 = 2/3 (simplified)
So each friend gets 2/3 of a brownies
