Answer:
sum of exterior angles of polygon = 360°
therefore,
z = 360 - (105+145)
z = 360 - 250
z = 110°
fales that is never gonna be proofen right
Answer:

Step-by-step explanation:
Given that,
The frequency of x-rays, 
We need to find the wavelength for x-rays. The relation between wavelength, frequency and speed of light is given by :

So, the wavelength for x-rays is
.
