For PART A: the height of the pole in the right angle triangle is 30 ft and the correct option is C

For PART B: the lenght of wire 1 in the right angle triangle is 45 ft and the right option is D

<h3 /><h3>What is a right angle triangle?</h3>

A right-angled triangle is a polygon of three sides having one angle as 90 degrees(right angle).

Part A

To calculate the height of the pole in the right angle triangle, we use the formula below.

Formula:

  • tan∅ = opposite/adjacent

From the diagram,

Given:

  • ∅ = 41°
  • Opposite = Height of the pole = P
  • Adjacent = 34 ft

Substitute these values into equation 1 and solve for P

  • tan41° = P/34
  • P = 34×tan41°
  • P = 29.55
  • P ≈ 30 ft

Part B

Similarly, fine the length of wire 1, we use the formula below.

Formula:

  • cos∅ = Adjacent/Hypotenus.......... Equation 2

From the diagram,

Given:

  • Hypotenus = Wire 1 = x
  • ∅  = 41°
  • Adjacent = 34 ft

Substitute these values into equation 2 and solve for x

  • cos41° = 34/x
  • x = 34/cos41°
  • x = 45.05
  • x ≈ 45 ft

Hence, the height of the pole is 30 ft and the lenght of wire 1 is 45 ft.
