The sum of the measures of the exterior angles of a polygon, taken one per vertex, is 360.

z - 13 + z + 10 + z = 360

3z - 3 = 360

3z = 363

z = 121

z - 13 = 121 - 13 = 108

Answer: z - 13 = 108 degrees

What is the value of 2 over 3 to the power of 0 to the power of -3

Schach [20]

Answer:

$((\frac{2}{3})^0)^{-3}=1$

Step-by-step explanation:

We need to find the value of $((\frac{2}{3})^0)^{-3}$

Solving:

We know, $(a^b)^n = a^{b*n}$

$((\frac{2}{3})^{0*-3})$

$(\frac{2}{3})^0$

a^0 = 1

so,

$(\frac{2}{3})^0=1$

So, the value of $((\frac{2}{3})^0)^{-3}=1$

What is 10 squared plus b squared equals 22 squared

klio [65]

I'm pretty sure you are asking for the value of b. Let's actually write it and then solve it:
$10^2 + b^2 = 22^2$

Solving for b yields:
$b = \sqrt{22^2-10^2} = \sqrt{484-100} = \sqrt{384} = 19.59$

So, b = 19.59. If you want the answer in simplified radical form, we can also do that:
$\sqrt{384} = \sqrt{16*24} = 4 \sqrt{24} = 4 \sqrt{4*6} = 8 \sqrt{6}$

So, b = 8√6 = 19.59
