A maple tree is 16 yards tall and its shadow is 12 yards long. A nearby observation tower is 12 yards tall. How long is the obse

pashok25 [27]

Answer: 9 yards

Step-by-step explanation:

Given

The maple tree is 16 yards tall and its shadow is 12 yards tall

Suppose the angle made by the maple tree is x

$\Rightarrow \cos x=\dfrac{12}{16}$

For the tower also, the angle made by the tower and its shadow is x

Suppose the length of the shadow is y

$\Rightarrow \cos x=\dfrac{y}{12}$

Substitute the value of $\cos x$

$\Rightarrow \dfrac{y}{12}=\dfrac{12}{16}\\\\\Rightarrow y=9\ \text{yards}$

Perform the following operations and write the answers in radical form. Part A:√7+√3+√98−√18 Part B:3√5−3√11+2√121−3√90

Sveta_85 [38]

Answer:

$\sqrt{7}+\sqrt{3}+4\sqrt{2}$
$3\sqrt{5}-3\sqrt{11}+22-9\sqrt{10}$

Step-by-step explanation:

Part A ;

$\sqrt{7} +\sqrt{3} +\sqrt{98} -\sqrt{18} \\\\\sqrt{98}=7\sqrt{2}\\\sqrt{18}=3\sqrt{2}\\\\=\sqrt{7}+\sqrt{3}+7\sqrt{2}-3\sqrt{2}\\\\\mathrm{Add\:similar\:elements:}\:7\sqrt{2}-3\sqrt{2}=4\sqrt{2}\\\\=\sqrt{7}+\sqrt{3}+4\sqrt{2}$

Part B ;

$3\sqrt{5} - 3\sqrt{11} + 2\sqrt{121} -3\sqrt{90} \\\\2\sqrt{121}=22\\3\sqrt{90}=9\sqrt{10}\\\\=3\sqrt{5}-3\sqrt{11}+22-9\sqrt{10}$

In the figure, use similar triangles and the fact that corresponding sides are proportional to find the missing length.

Phoenix [80]

Answer:

<u><em>The missing length, x, is equal to 7 m.</em></u>

Explanation:

In the figure, the two triangles are similar because they show two pairs of congruent angles and one pair of different sides.

The two upper vertices are marked each with a line which indicates that they are congruent, i.e. they have the same measure.

Also, the small squares shown in each of the bases indicate that those two angles are right, i.e. they measure 90°.

Since the two sides adjacent to the right angles have different lengths, the triangles are not congruent but similar.

By similarity, you can state that the corresponding parts keep the same ratio. Thus:

x / 8m = 21m / 24m

x = 8m × 21 m / 24 m (muliply both sides by 8m)

x = 21 m / 3 (simplify dividing numerator and denominator by 8m)

x = 7 m (simplify dividing by 3)

Answer x = 7 m
