This is how you can obtain your goals. following are one of the answer and question example that you can potentially utilize to practice and supercharge your understanding and also give you insights that would help you to maintain your study in school.

## Question:

What is the length of MN

## Answer:

**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.]

Subtract x from both sides , we get

Divide bothe sides by x , we get

1= x or x =1

**Then, the length of MN
=** x+3=1+3=4 units

They could certainly hopefully guide the student deal with the question by obtaining the questions and answer examples. Then could have some sharing in a group discussion and also study with the classmate with regard to the topic, so another student also experience some enlightenment and still keeps up the school learning.
