Answer:

A. Right triangle

Step-by-step explanation:

For problems like this, make use of the Pythagorean Theorem to determine which triangle can be formed.

Thus, there are always 3 sides in a ∆, as we've been given in the question above. The following rule can be use to find out which triangle can be formed:

1. If a² + b² = c², a right triangle is formed.

2. If a² + b² > c², an acute triangle is formed.

3. If a² + b² < c², an obtuse triangle is formed.

Where, c is always the longest side, while a and b are the 2 other shorter side lengths compared to c.

From the question given,

a = 24

b = 45, while

c = 51

Let's find out which of the 3 rules this side lengths fit in, to determine the triangle they form.

24² + 45² ? 51²

576 + 2025 ? 2601

2601 = 2601 (this fits into rule 1 stated above)

Therefore, the side lengths given in the question would form a right triangle.

In a designated VIP seating section there must be an odd number of seats in each row and each row must have two more seats than

Vikki [24]

Let n be the total number of rows and there are x seats is the 1st row where x is an odd natural number.

As each row must have 2 more seats than the one before it, so

Number of seats in 2nd row = x+2

Number of seats in 3rd row = x+2+2=x+2x2

Number of seats in 4th row = x+2+2+=x+2x3

Similarly, the number of seats in (n-1)th row =x+2x(n-1)

the number of seats in n^{th} row, i.e last row =x+2x n.

As the front row must have one-quarter of the total seats in the back 2 rows combined, so

$x =\frac 1 4 ( x+2\times(n-1) + x+2\times n) \\\\\Rightarrow 4x=2x+4n-6 \\\\\Rightarrow 4x-2x=4n-6 \\\\\Rightarrow 2x=4n-6 \\\\\Rightarrow x=2n-3\cdots(i)$

So, the number of seats in the 1st row, x, and the total number of seats, n, must satisfy the equation (i).

For $x>0, n\geq 3.$

So, for n=3 rows

The number of seats in the 1st row, x= 2x3-3=3.

The number of seats in the 2nd row, = 3+2=5 as in subsequent rows, there will be 2 more seats.

and the number of seats in the 3rd row (last row)=5+2=7.

n can have any integral values satisfying $n\geq 3$ .
