I WILL MARK BRAINLIEST PLEASE HELP !! Determine whether the two triangles are similar.
soldi70 [24.7K]

The two triangles are similar by SSA similarity. Option B is correct.

<h3>What is the triangle?</h3>

A triangle is a three-sided polygon. It is one of the most fundamental geometric forms.

If the ratio of the sides are same as well as the one angle is common between the two triangles then in that condition there will be SSA similarity.

From the triangle ABC and DEC

The ratio of the sides is;

\rm  \frac{10}{12}= \frac{8}{9.6} \\\\ \frac{5}{6}= \frac{5}{6}

One angle c is common in the two triangles.

The two triangles are similar by SSA similarity.

Hence, option B is correct.

New York City is approximately 205 miles from Washington, D.C. How far apart will these cities appear on a map with the scale 1
gavmur [86]

Answer: 4.1 inches

Step-by-step explanation:

From the question, we are informed that New York City is approximately 205 miles from Washington, D.C.

The distance that these cities will appear on a map with the scale 1 in: 50 miles will be represented by x.

Therefore, x:205 = 1:50

Cross multiply

x/205 = 1/50

50x = 205

x = 205/50

x = 4.1 inches

The answer is 4.1 inches
