1. Joshua has a ladder that is 15 ft long. He wants to lean the ladder against a vertical wall so that the top of the ladder is 14.8 ft above the ground. For safety reasons, he wants the angle the ladder makes with the ground to be no greater than 70°. Will the ladder be safe at this height (2 points)? Show your work and draw a diagram to support your answer

Unsafe; angle with ground > 70°.

Step-by-step explanation:

Data:

a = 15    ft

b = 14.8 ft

A = 90°

Calculation:

We can use the Law of Sines.

The ladder will be unsafe because its angle with the ground is greater than 70°.

fahrenheit

step-by-step explanation:

fahrenheit is more precise than celsius. the ambient temperature on most of the inhabited world ranges from -20 degrees fahrenheit to 110 degrees fahrenheit—a 130-degree range. on the celsius scale, that range is from -28.8 degrees to 43.3 degrees—a 72.1-degree range. this means that you can get a more exact measurement of the air temperature using fahrenheit because it uses almost twice the scale.
