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:
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.

First, you want to add up the subtotal together, so its 5.54+2.49+3.73, and adding those together you get 11.76 as your subtotal. To figure out change, you simply subtract your subtotal to the amount he paid in. For that it is 20-11.76, and that is 8.24
Elliot gets $8.24 in change.
Hope this helps.

Answer:
18: x=2 y=2.5
19: y = 0.5
Step-by-step explanation:
2(2)=4
2.5(2)=5
4+5=9
2×0.5=1
