Answer: 43.02 miles (Approx)

Step-by-step explanation:

Let the entire situation is shown by a triangle CAB,

In which A shows Almondville, B shows Walnut Grove and C shows Pecan City.

Also, D\in BC such that AD\perp BC

Thus, According to the question, AB = 52.4 miles

AC = 75.3 miles and BC = 91.7 miles.

And, We have to find out AD = ?

Since, CAB and CDA are right angle triangles.

Where, ∠CAB≅∠CDA

∠ACB≅∠ACD

Thus, By AA similarity postulate,

\triangle CAB\sim \triangle CDA

Therefore, by the property of similarity,

\frac{AB}{DA} = \frac{CB}{AC}

⇒ \frac{52.4}{DA} = \frac{91.7}{75.3}

⇒ DA= \frac{75.3\times 52.4}{91.7}

⇒  DA= \frac{3945}{91.7}

⇒  DA= 43.0285714286≈ 43.02 miles

Thus, the shortest length possible for that road= 43.02 miles (approx)

Suppose that during one period extreme cold,the average daily temperature decreased 1 1/2 F each day. How many days did it take
Alenkasestr [34]

We have been given that during one period extreme cold, the average daily temperature decreased 1\frac{1}{2} degree F each day. We are asked to find number of days it will take for the temperature to decrease by 9 degree F.

First of all we will convert our mixed fraction into improper fraction.

1\frac{1}{2}=\frac{3}{2}

Now we will divide total temperature change (9) by average daily temperature change (\frac{3}{2}) to find number of days.

9\div\frac{3}{2}

Dividing a number by a fraction is same as multiplying the number by reciprocal of the fraction.

9\cdot\frac{2}{3}

3\cdot2=6

Therefore, it will take 6 days for the temperature to decrease by 9 degree F.

State the third congruent part to prove the two triangles congruent by SSS. Write the triangle congruence statement
Alekssandra [29.7K]

Answer:

  • ΔCBA ≅ ΔDEF

Step-by-step explanation:

The question in text and on the picture are different.

Going by picture.

When stating the congruence, it is important to stick to right order of vertices.

The first triangle is ΔCBA

<u>Corresponding angles are:</u>

  • ∠C ≅ ∠D, ∠B ≅ ∠E, ∠A ≅ ∠ F

<u>Therefore the second triangle is:</u>

  • ΔDEF
