A triangle has an altitude with height 7 cm. Which of the following have a proportional relationship to the height? Select all that apply. The perimeter
The sides
The angles

I think is perimeter, area and sides.
But I’m not sure. Please help. Thanks

Formulate the indicated conclusion in nontechnical terms. be sure to address the original claim. the foundation chair for a hospital claims that the mean number of filled overnight beds is over 523, and she is therefore justified starting a funding campaign to add a wing to the hospital. assuming that a hypothesis test has been conducted and that the conclusion is failure to reject the null hypothesis, state the conclusion in nontechnical terms.
