Solve the right triangle. round decimal answers to the nearest tenth.

AB = 15 A = 36.9 B = 53.1

Step-by-step explanation:

A2 + B2 = C2

12(2 + 9(2 = 144 + 81 or 225 = C2

sqaure 225 to get rid of the exponent

so C = 15 or AB = 15

Divide your Oppisite by Hypo so 9/15 = .6

then use x = sin-1(0.6) to find angle A or 36.9

then add 36.9 to 90 and minus that from 180

so 180 - 126.9 = 53.1

john has 55 candy left.

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.
