10 in<br> Given the figure. Find AC.
rjkz [21]

Answer:

if its an arc and center angle is given it could be double the size. IF it is a triangle measure you would use Pythagoras for triangle and trig for given angle, if two triangles are shown and they are scale of each other alternative measures given divide into each measure by the correct line and check this with the matching angles. when found as a division this is the ratio so then you just multiply to find the larger measure but divide to find the smaller measure. AC could also be a junction or vector, if its a type of vector then you just follow the arrows and count how many arrows fit the line pick a direction and ie) if its x2 a then you show a+a.

A reflecting pool is shaped like a right triangle, with one leg along the wall of a building. The hypotenuse is
maria [59]

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,

x^2+(x+7)^2=(x+9)^2,\\ \\x^2+x^2 +14x+49=x^2+18x+81,\\ \\x^2-4x-32=0,\\ \\D=(-4)^2-4\cdot 1\cdot (-32)=16+128=144,\\ \\x_{1,2}=\dfrac{-(-4)\pm\sqrt{144}}{2\cdot 1}=\dfrac{4\pm12}{2}=-4,\ 8.

The length of the side cannot be negative, thus x=8 ft. Then x+7=15 ft, x+9=17 ft.

From the top of a vertical cliff 50 m high, the angle of depression of an object that is level with the base of the cliff is 70°
Svetlanka [38]

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 = \dfrac{\textrm perpendicular}{\textrm base}

I.e TanФ = \dfrac{\textrm AB}{\textrm OA}

Or, TanФ = \dfrac{\textrm h}{\textrm x}

Or, Tan 70° = \dfrac{\textrm 50 meters}{\textrm x meters}

Or, 2.74 = \dfrac{\textrm 50}{\textrm x}

∴ x =  \dfrac{\textrm 50}{\textrm 2.74}

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
