Answer:

a)

<u>The equation would be:</u>

  • 3x + 2 = 7*2

b)

Step 1. <u>Subtract 2 from both sides:</u>

  • 3x = 6*2

Step 2. <u>Divide both sides by 3:</u>

  • 3x/3 = 6*2/3
  • x = 2*2

c)

  • A single box weights x= 4 units.

<u>a) Solution:</u>

The equation that is represented by the diagram below will be,

→ 3x + 2 = 7 × 2

<u>b) Solution:</u>

The steps that can be taken are,

→ 3x + 2 = 7 × 2

→ 3x = 14 - 2

→ 3x = 12

→ x = 12/3

→ [x = 4]

<u>c) Solution:</u>

A single box weighs 4 units (kg), because the required value of x is 4.

A pole 5 feet tall is used to support a guy wire for a tower, which runs from the tower to a metal stake in the ground. After pl
sammy [17]

The length of the guy's wire to the nearest foot is 89 feet.

The situation forms a right-angled triangle.

<h3>Properties of a right angle triangle:</h3>
  • A right-angle triangle has one angle of 90 degrees.
  • The sides can be found using the Pythagoras theorem.
  • The angles can be found using trigonometric ratios.

The hypotenuse of the triangle is the length of the wire.

let's use the smaller triangle to find the angle opposite the tower. Therefore,

tan ∅ = opposite / adjacent

tan ∅ =  5 / 2

∅ = tan⁻¹ 2.5

∅ = 68.1985905136

∅ = 68.20°

Therefore,

cos 68.20 = adjacent / hypotenuse

cos 68.20 = 33 / hypotenuse

hypotenuse = 33 / cos 68.20

hypotenuse = 88.8606843161

Therefore,

length of wire ≈ 89 feet.
