The picture below shows a right-triangle-shaped charging stand for a gaming system: the side face of a charging stand is a right

triangle labeled abc. The measure of angle acb is 90 degrees, and the measure of angle abc is 50 degrees. Side bc measures 3 inches. Which expression shows the height, ac, of the charging stand? 3 over cos 50 degrees 3(tan 50°) 3 over tan 50 degrees 3(cos 50°).

The expression for the height of the stand is:

ac = 3in*tan(50°).

<h3>How to get the height of the charging stand?</h3>

We have the right triangle abc.

We know that:

  • c = 90°
  • b = 50°
  • bc = 3 inches.

We want to get the length of ac.

Notice that ac is the opposite cathetus to angle b, which measures 50°.

Then we can use the trigonometric relation:

tan(a) = (opposite cathetus)/(adjacent cathetus).

Then we will have:

tan(50°) = ac/bc

We can replace bc by its length:

tan(50°) = ac/3in

3in*tan(50°) = ac.

This is the expression for the height of the stand.

kupik [55]

Answer:

The answer is based off of the second paragraph of the 2nd source:

One development that was vital to the principle of equality was the American and French revolutionaries not conforming to traditional ways of life. For example, the revolutionaries expanded the “whole horizon of age.” This allowed more people to conform to their own agendas and not be suffocated by the “royal charisma.”

Explanation:

I am pretty sure this will give you the general idea of one of the actions took by revolutionaries to allow some form of equality. I would suggest putting this general statement into your own words to avoid any issues just in case my answer isn't sufficient :)

What is the molarity of a solution that contains 5.80 grams of nickel (ii) nitrate in 500. ml?
Rus_ich [418]

Answer:- 0.0634 M

Explanation:

molarity is defined as the number of moles of solute in 1 L of solution

molar mass of Ni(NO₃)₂ - 182.7 g/mol

number of moles of Ni(NO₃)₂ - 5.80 g/ 182.7 g/mol = 0.0317 mol

number of moles in 500 mL - 0.0317 mol

therefore number of moles in 1000 mL - 0.0317 mol / 500 mL x 1000 mL/L

molarity of the solution is - 0.0634 M
