Answer :

Answer: Radius of a solid aluminium sphere is 3.67 cm.

Step-by-step explanation:

4/3 · 2.57³ π · 7,860 = 4/3 · r³ π · 2,700  / : 4/3 π

2.57³ · 7860 = r³ · 2,700

r³ = 2.57³ · ( 7,860 : 2.700 ) = 2.57³ · 2.911111...    /∛

r ≈ 2.57 · 1.428 = 3.67 cm

Triangle ABC and DEF are right triangles, as shown. Triangle ABC is similar to triangle DEF. which ratios are equal to sin C?
Dafna11 [192]

Answer:

First option and Fourth option.

Step-by-step explanation:

To solve this exercise you need to use the following Trigonometric Identity:

sin\alpha=\frac{opposite}{hypotenuse}

In this case you know that:

\alpha =C

Since triangle ABC is similar to triangle DEF:

\angle C=\angle F

Let's begin with the triangle ABC.

You can identify that:

opposite=AB\\hypotenuse=AC

Then, substituing values, you get:

sinC=\frac{AB}{AC}

In triangle DEF, you know that:

opposite=DE\\hypotenuse=DF

So, substituing values, you get:

sinF=sinC=\frac{DE}{DF}

Which piece of additional information can be used to prove △CEA ~ △CDB?
8_murik_8 [283]
<h3>Answer:</h3>

∠BDC and ∠AED are right angles

<h3>Step-by-step explanation:</h3>

Because ∠C ≅ ∠C, the additional bit of information above can be used to show AA similarity.

____

None of the other offered choices says anything about <em>both</em> triangles. In order to show similarity, you need information about corresponding parts of the <em>two</em> triangles. Information about one triangle alone is not sufficient.
