Answer:

  • See below

Step-by-step explanation:

Set proportions and solve

1a.

  • 333/37 = x/55 ⇒ x = 55*9 ⇒ x = 495 miles

1b.

  • 308/5 = x/ 3 ⇒ x = 61.6*3 ⇒ x = 184.8 miles

2a.

  • 428/107 = x/17 ⇒ x = 4*17 ⇒ x = 68 km

2b.

  • 1 / 9 = x / 288 ⇒ x = 288 / 9 ⇒ x = 32 kg

In an equilateral triangle, the measure of each angle is 60 degrees. Then the value of x and y is 17/3 and 65.

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

A triangle is a three-sided polygon with three angles. The angles of the triangle add up to 180 degrees.

In trianlge ΔMNP, PM = 3x - 4, MN = 14, ∠N = 5y - 5.

In an equilateral triangle, all the sides and all the angles are equal.

MN = NP = PM

∠M = ∠N = ∠P

Then we have

   PM = MN

3x - 4 = 14

      x = 17/3

We know in an equilateral triangle, the measure of each angle is 60 degrees. Then we have

    ∠N = 60

5y - 5 = 60

    5y = 65

      y = 13
