Answer:
Step-by-step explanation:
We require 2 equations with the repeating decimal after the decimal points.
let x = 2.3333... → (1) ← multiply both sides by 10
10x = 23.333..... → (2)
Subtract (1) from (2), thus eliminating the repeating decimal
9x = 21 ( divide both sides by 9 )
x = =
Answer:
A. 60°
Step-by-step explanation:
3tan^3 x= tan x
3tan^2x = 1
tan^2 x = 1/3
tan x = 1/
x = 60°
Answer:
16 degrees
Step-by-step explanation:
2x+6 = 38
-6 -6
