Step-by-step explanation:
Pretty sure it's correct
To get an answer which is....45
Answer:
False
Step-by-step explanation:
A subset is a set whose elements belong to another set
If B is a subset of A, B would contain elements of A
For example, A = {a, b, c} and if B is a subset of A , B = { a, b}
There is a little-known theorem to solve this problem.
The theorem says that
In a triangle, the angle bisector cuts the opposite side into two segments in the ratio of the respective sides lengths.
See the attached triangles for cases 1 and 2. Let x be the length of the third side.
Case 1:
Segment 5cm is adjacent to the 7.6cm side, then
x/7.6=3/5 => x=7.6*3/5=
4.56 cm
Case 2:
Segment 3cm is adjacent to the 7.6 cm side, then
x/7.6=5/3 => x=7.6*5/3=
12.67 cmThe theorem can be proved by considering the sine rule on the adjacent triangles ADC and BDC with the common side CD and equal angles ACD and DCB.
