Question

What is the length of A. 7 B. 4 C. 8 OD. 1 3 X +3 ? What is the length of A. 7 B. 4 C. 8 OD . 1 3 X +3 ?​

Answer 1

Answer: 4

Explanation:

Sides opposite congruent angles in a triangle are congruent, so:

• 4x = x + 3
• 3x = 3 [subtract x from both sides]
• x = 1 [divide both sides by 3]

So, MN = 1 + 3 = 4
