Answer:

  π/10 in/s ≈ 0.314 in/s

Step-by-step explanation:

The circumference of the circle it traverses is given by the formula ...

  C = 2πr

Substituting the given radius, we find the distance traveled in 60 seconds to be ...

  C = 2π(3 in) = 6π in

Then the linear speed is ...

  speed = distance/time = (6π in)/(60 s) = π/10 in/s

We are given an isosceles triangle.

An isosceles triangle has corresponding angles of corresponding sides same.

<em>Therefore, other angle is also of (3x+7) degrees.</em>

(5x+13) and (3x+7) makes a linear pair.

Therefore,

(5x+13) + (3x+7)  = 180

5x +13 + 3x +7 = 180.

8x +20 = 180.

Subtracting 20 from both sides, we get

8x +20-20 = 180-20.

8x = 160

Dividing both sides by 8, we get

<h3>x = 20.</h3><h3>Therefore, correct option is 3rd option. </h3>
