Ireally need to find x were are on properties of tangent

15√2

Step-by-step explanation:

Tan 45° = 1, and tan = (opposite side)/(adjacent side)

We can set up an equation as follows...

tan 45° = x/(15√2)

Solve it...

1 = x/(15√2)

  multiply both sides by 15√2 to isolate 'x'

15√2(1) = (15√2)x/(15√2)

   15√2 = x       ( the 15√2 in the numerator and denominator cancel out)

answer:

the position of equilibrium will shift to the left.

step-by-step explanation:

the general equation for the dissociation of a weak base is

b + h₂o   ⇌   bh⁺ + oh⁻

according to le châtelier's principle, when a stress is applied to a system at equilibrium, the system will respond in a way that tends to relieve the stress.

if you apply a stress by adding more bh⁺ or oh⁻,   the system will respond by moving in a direction that gets rid of the added ions.

the position of equilibrium will shift to the left, forming more of the undissociated base.

the answer to the expression is 83
