Answer: D. 4
Step-by-step explanation:
In the given picture , we have given a triangle ΔMLN in which
ML= 4x and MN= x+3
∠L=∠N=50°
⇒ MN=ML [∵ Basically by Isosceles triangle property :sides opposite to equal angles of a triangle area equal.]
![\Rightarrow\ x+3=4x](https://tex.z-dn.net/?f=%5CRightarrow%5C%20x%2B3%3D4x)
Subtract x from both sides , we get
![3=3x](https://tex.z-dn.net/?f=3%3D3x)
Divide bothe sides by x , we get
1= x or x =1
Then, the length of MN
= x+3=1+3=4 units
