Answer:
Option 3) 24 is right.
Step-by-step explanation:
Given in the picture is a triangle LMN. sides are MN = 12, LN = 21 and LM = x cm
Also MO is the angle bisector of angle M.
By applying angle bisector theorem for triangles we get
LM/MN = LO/NO
i.e. x/12 = 14/7
Simplify to get x = 24
Hence option 3 is right
Verify:
Check whether angle bisector theorem is true.
The proportion LM/MN =24/12 = 2
The proportion LO/NO =14/7 =2
Both are equal and hence verified
The LCM of 6,2,and 22 is 66.
Happy studying ^-^
Answer:
See explanation
Step-by-step explanation:
Consider triangles CAX and BAX. In these triangles,
- - given
- - given
- - reflexive property
By SAS postulate,
Congruent triangles have conruent corresponding parts. So,
Consider triangles CXY and BXY. In these triangles,
- - proven
- - given
- - reflexive property
By SAS postulate,
Congruent triangles have conruent corresponding parts. So,
The slope is this and that
