It looks like it wants the arc length of the circle from point P to point E. Use the fact that there are 360 deg in a circle being subdivided by the five points of the pentagon.

25/5=3

3×3=9

25+3+9=37

There are 37 fish.

**Answer:**

**The dimension of the cardboard is 34 cm by 34 cm by 17 cm.**

**Step-by-step explanation:**

Let the dimension of the cardboard box be x cm by y cm by z cm.

The surface area of the cardboard box without lid is

f(x,y,z)= xy+2xz+2yz**.....(1)**

Given that the volume of the cardboard is 19,652 cm³.

Therefore xyz =19,652

**......(2)**

putting the value of z in the equation (1)

The partial derivatives are

To find the dimension of the box set the partial derivatives and .Therefore

**.......(3)**

and

**.......(4)**

Now putting the x in equation (3)

⇒y=34 cm

Then =34 cm.

Putting the value of x and y in the equation (2)

=17 cm.

**The dimension of the cardboard is 34 cm by 34 cm by 17 cm.**

Question 1: Answer D - 4th degree trinomial

Question 2: Answer D - IV, I, II, III

**Answer:**

Point W

**Step-by-step explanation:**

Planes A and B intersect at an angle. Intersection of lines is when two lines meets at a particular point and cuts each other at the same point. Its a measure of perpendicularity for right angles and greater or lesser for others.

At any point W, line m and line n cuts each other at point W to form an angle as shown from the diagram.
