If you need to refer to the figure you can open the pdf file that I attached.

If you do not know the relationship between arc lengths and angles in radians, you can derive it from the circumference of a circle. This is how:

[2π rad / 2π R] = [x / arc] , where R is the radius of the circle, arc is the length of the arc, and x is the angle in radians.

You can solve for the angle x.

x = arc / R

In the figure arc = 15.5 inches, R = 12 inches, and theta is the unknown angle. Then:

theta = arc / R = 15.5 / 12 = 1.29167 radians.

Which rounded to the nearest hundreth is 1.29

Answer: 1.29 radians

The answer to your question is below

Step-by-step explanation:

Data

4 red marbles

3 blue marbles

3 yellow marbles

a) Total number of marbles = 4 + 3 + 3 = 10 marbles

b) Number of red marbles = 4 marbles

c) Number of blue marbles = 3 marbles

d) P(blue) = number of blue marbles/ total number = 3/10

e) P(red) = number of red marbles/total number = 4/10 = 2/5

The missing length $x=\frac{12}{5}$ .

Solution:

The image of the answer is attached below.

In figure ABCD, AB = 4, BC = 10

In figure PQRS, PQ = x, RS = 6

Given figures are similar.

If two figures are similar, then the sides are proportionate to each other.

⇒ $\frac{AB}{BC}= \frac{PQ}{QR}$

⇒ $\frac{4}{10}= \frac{x}{6}$

Do cross multiply.

⇒ $4 \times 6 = x \times 10$

⇒ $24 = 10x$

⇒ $x=\frac{24}{10}$

To reduce the length, divide both numerator and denominator by 2.

⇒ $x=\frac{12}{5}$

Hence, the missing length $x=\frac{12}{5}$ .
