Answer:
C. 5
Step-by-step explanation:
∆LMN kid an isosceles triangles because it has two base triangles that are equal to each other. Therefore, the sides opposite the base triangles would also be equal to each other.
Thus:
3x = x + 10
Solve for x. Subtract x from each side
3x - x = 10
2x = 10
Divide both sides by 2
x = 5
Area = 2 x 8 + 4 x 2 = 16 + 8 = 24in²
Answer: 24 in²

<h3>How to solve for permutations and combinations</h3>
1. The letters of the word track can be arranged in 5! ways
These are 5 x 4 x 3 x 2 x1
= 120
2. The way that the student would be able to select 6 out of 10 questions would be by 10C6
= 210 ways
