I don't understand this question, picture attached.

We can find this using the formula for arc length (where $r$ is the radius of the circle and $\theta$ is the central angle in radians):

$\textrm{Arc Length} = r\theta$

In our problem, we are given $12 = 8\theta$ . This means that:

$\theta = \dfrac{12}{8} = \boxed{\frac{3}{2}}$

The measure of the angle is 1.5.

How to solve 2x(x+3)=2x^2+15

Travka [436]

Answer: x = 5/2 = 2.5

Step-by-step explanation:

Given expression

2x (x + 3) = 2x² + 15

Expand parentheses and apply the distributive property

2x · x + 2x · 3 = 2x² + 15

2x² + 6x = 2x² + 15

Subtract 2x² on both sides

2x² + 6x - 2x² = 2x² + 15 - 2x²

6x = 15

Divide 6 on both sides

6x / 6 = 15 / 6

x = 15/6

$\boxed{x=\frac{5}{2} }$

Hope this helps!! :)
