Answer:
8 ft, 15 ft, 17 ft
Step-by-step explanation:
Let x feet be the length of the side along the building. If the hypotenuse is 9 feet longer than the side along the building, then the length of the hypotenuse is x+9 feet. If the third side is 7 feet longer than the side along the building, then the length of the third side is x+7 feet.
This triangle is right triangle. By the Pythagorean theorem,
The length of the side cannot be negative, thus x=8 ft. Then x+7=15 ft, x+9=17 ft.
Answer:
The distance of the object from the base of cliff is 18.24 meters
Step-by-step explanation:
Given as :
The height of the vertical cliff = h = 50 meters
The distance of the object from the base of cliff = x meters
Let The angle of depression of object that level with cliff base = Ф = 70°
<u>Now, from figure</u>
Tan angle =
I.e TanФ =
Or, TanФ =
Or, Tan 70° =
Or, 2.74 =
∴ x =
I,e x = 18.24 meters
So, The distance of the object from the base of cliff = x = 18.24 meters
Hence,The distance of the object from the base of cliff is 18.24 meters Answer
