41.9 mi

Step-by-step explanation:

First, we convert the angle from degree measure to radian measure:

$\theta = 240°×\left(\dfrac{\pi}{180°}\right)= \dfrac{4\pi}{3}\:\text{rad}$

Using the definition of an arc length $s$

$s = r\theta$

$\:\:\:\:=(10\:\text{mi})\left(\dfrac{4\pi}{3}\:\text{rad}\right)$

$\:\:\:\:= 41.9\:\text{mi}$

Simplify the expression square root of -25/(5-2i) + (1-3i)

Georgia [21]

Answer:

I guess $\frac{25}{6} -5i$

Step-by-step explanation:

$\frac{-25}{(5-2i)+(1-3i)}$ 1. rewrite the expression(it helps me tbh)

$\frac{-25}{5 - 2i+1-3i}$ 2. Distribute the positive symbol to (1-3i)

$\frac{25}{6-5i}$ 3. treat i as a variable while you combine like terms

$\frac{25}{6} -5i$ 4. divide 25 by 6-5i but leave 25/6 as a fraction since it can't be divisible.
