Answer:
x = -1/9
Step-by-step explanation:
first let's think of x as 1x so than x^2 is basically 1x.
you bring down 8x + 1 = 0 so you have x + 8x + 1 = 0.
than you add x and 8x which equals 9x.
you bring the problem down one more time so 9x + 1 = 0.
you subtract 1 from each side so the 0 becomes because 0 - 1 is -1.
So than you bring the rest of the problem down 9x = -1
Last thing you do is divide 9 from both sides which x = -1/9.
Answer:
x ≈ 33.1°
Step-by-step explanation:
Using the tangent ratio in the right triangle
tan x = 
= 
, then
x = 
( ) ≈ 33.1° ( to the nearest tenth )
