Answer:
![\frac{8}{9}](https://tex.z-dn.net/?f=%5Cfrac%7B8%7D%7B9%7D)
Step-by-step explanation:
we require 2 equations with the repeating digits placed after the decimal point.
let x = 0.888.. (1) ← multiply both sides by 10
10x = 8.888.. (2)
subtract (1) from (2) thus eliminating the repeating digits
9x = 8 ( divide both sides by 9 )
x = ![\frac{8}{9}](https://tex.z-dn.net/?f=%5Cfrac%7B8%7D%7B9%7D)
Answer:
c
Step-by-step explanation:
Using the correct order of operations, your equation would simplify as:
-36 - 10 = -26
LHS: cos^2 A( 1+cot^2A)
=cos^2A(cosec^2A) ,1+cot^2A=cosec^2A
=cos^2A( 1/sin^2A)
=(cos^2A/ sin^2A)
=cot^2A
=RHS
Hope this can help.
