Answer 1

Answer:

1.Zero

2.x=2

3.1080°

Expalnation :- Octagon is a polygon with 8 sides. For an n-sided polygon, the formula to calculate the sum of interior angles is given by (n - 2) × 180°. So, since the octagon has 8 sides, the sum of the interior angles will be (8 - 2) × 180° = 1080°.

4.2/2

5. -113

Answer 2

Step-by-step explanation:

Solutions :-

1)

The reciprocal of zero does not exist

Reason :-

The reciprocal of 0 = 1/0 = undefined

Division by zero is meaning less

2)

Given equation is X(2X-3) = 2X(X-4)+10

=> 2X²-3X = 2X²-8X+10

=> 2X²-3X-2X²+8X = 10

=> -3X+8X = 10

=> 5X = 10

=> X = 10/5

=> X = 2

Therefore, X = 2

3)

Given polygon = Octagon

Number of sides in the octagon = 8

We know that

The sum of interior angles in a regular polygon of n sides is (n-2)×180°

The sum of interior angles of a regular octagon

=> (8-2)×180°

=> 6×180°

=> 1080°

The sum of measure of interior angles of a regular octagon is 1080°

4)

Honesty is the best policy the probability of this events is 1

5)

Given number = 1 2/8 = 10/8 = 5/4

The multiplicative inverse of 5/4 = 1/(5/4) = 4/5
