( Don't cheat, use your own words) He is correct. 9 x 8 = 72
He can check his math by doing 72 ÷ 9 = 8 and 72 ÷ 8 = 9
A.) m∠EBD = m∠EBC - m∠CBD = 140 - 35 = 105
m∠ABE = 180 - m∠EBC = 180 - 140 = 40
b.) no because the angle measure is not 90 degrees
Answer:
806 million years
Step-by-step explanation:
From the information given:
Firstly, we need to determine the no. of ways we can choose n many words in the dictionary & array them in
ways.
Thus, the no. of unique books possible of length till K is:

where K = 6, we have the value to be:
= 25420530373932821216635722990977
Thus, the time required to write all possible texts of 6 is:
= (25420530373932821216635722990977)/10⁶
≅ 806 million years.
