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
It is not a sum, it is a product.
3 times x = 24 (write equation)
3x = 24 (isolate x by dividing the coefficient, 3, on both sides)
/3 /3
x = 8 (this i your answer)
Therefore 3 times 8 gives you 24.
Answer:
4
Step-by-step explanation:
6 - x/10 = -3
6 = -3 + x/10
9 = x/10
90 = x
