In the trial conducted after the triangle shirtwaist factory fire, new york city fire marshal william l. beers gave this testimony:

question: did you examine the fire-escapes of that building?
after the fire.
question: what did you find?
i found the fire-escape on the rear of the building, which was the only one, and was entirely inadequate for the number of people employed in that building.

how did testimony such as this from the triangle shirtwaist factory disaster affect the workplace?

state and federal governments began to take measures to protect the safety of workers.
factory owners were required to allow unions to take steps to protect worker safety.
the courts ruled that the government could not interfere in matters of workplace safety.
factory owners improved working conditions but cut wages and lengthened the workday.

The correct option is:

State and federal governments began to take measures to protect the safety of workers.

The Triangle Shirtwaist Factory fire (New York City, 1911) was one of the deadliest in U.S. history with 146 garment workers deaths. Because the access to the stairwells and exits were locked several of the workers who could not flee from the burning building jumped from the high windows. This fire led to legislation demanding better factory safety standards and helped push the growth of the International Ladies' Garment Workers' Union (ILGWU), which protested for safer working conditions for sweatshop workers.

b) race riots in several cities

the perimeter of a triangle is 69 cm. side a is 5 cm shorter than side b. side c is twice as long as side a. find the length of each side. i need to know how to do it in 2 equations.  

equations:

a = b-5

c = 2a

a + b + c = 69
