Answer:

x = 6

Step-by-step explanation:

According to Exterior Angle Property of a triangle , measure of an exterior angle is the sum of its opposite interior angles.

Using the exterior angle property ,

$17x - 23 = 3x + 17 + 8x - 4$

$= > 17x - 23 = 11x + 13$

$= > 17x - 13x = 23 + 13$

$= > 6x = 36$

$= > x = \frac{36}{6} = 6$

Can you please explain how to do this and give me the answer so next time I know how to do it. Square root with -15 in it and sq

Drupady [299]

Answer:

15i and 4i

Step-by-step explanation:

i is an imaginary number also shown as $\sqrt{-1}$ .

Since we have $\sqrt{-15}$ , thats 15* $\sqrt{-1}$ . Substitute $\sqrt{-1}$ for i and we get 15*i or 15i.

We do the same for $\sqrt{-4}$ . This is 4* $\sqrt{-1}$ or 4*i or 4i.

An easy way to do this is to take the negative inside the square root like $\sqrt{-6}$ , take the absolute value -6 absolute value=6 and times it by i. So now it becomes 6i
