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.

X = 20

This is an isosceles triangle so third angle is also 2x because of symmetry.
Angle sum = 5x + 2x + 2x = 9x = 180 degrees
