A ladder is leaned against the building. The bottom of the ladder is 9 feet from the building. The top of the ladder is 16 feet above the ground.

Answer:

slope=rise/run

the ladder rises 16 ft from the ground and runs 9 ft from the building. therefore…

-16/9=-1.7*repeating

You will need a scientific calculator for this.We use the trigonometric ratios,
Sin=opposite/hypotenuse Cos=adjacent/hypotenuse Tan=opposite/adjacent.Look at the angle of the slope and figure out which side is the opposite,hypotenuse and adjacent.In this case we have the opposite and the adjacent so find the formula which includes the two, which is tan=opp/adj, so in your calculator type 15/27 and then after the answer comes up, you should get 0.5 recurring now press the shift key and then press the tan key.You should get 29.0546… this is the slope in degrees
