4(5x+1)(5x-1) = 0
1. Take out the GCF (in this case, 4)
4(25x^2-1) = 0
2. This can be further factored. Factor the values within the parenthesis
4(5x + 1)(5x -1) = 0
Answer:
around 81.2 degrees
Step-by-step explanation:
use inverse tangent
remeber tan = O/H
divide it first
84/13
6.461538461538462
then use invese tan(
)
81.20258929000894
or around 81.2 degrees
