Step-by-step explanation:
A ladder leans against a building. The foot of the ladder is 2 feet from the building and reaches to a point 7 feet high on the building.
The ladder forms a right angle triangle with the building
Base of the triangle is 2 feet
The distance between the ground and the top of the ladder is 7 feet
the graph is attached below
AB= 2, AC = 7
We know the opposite and the adjacent side so we use tan formula

x = tan^-1 (7/2)
x = 74.05 degree
Answer:
Step-by-step explanation:
We need to evaluate if thickness of a 10 gauge metal sheet is a requiered in the process that means 3.416 mm thick. So that should be our null hypothesis; μ₀ = 3.416 and based on sample data, we will formulate an alternative hypothesis taking into account the mean, and standard deviation obtained. We surely will have better information to take a decision
