- The problem involves a right triangle where the adjacent side to the 43° angle is 35 m and the hypotenuse is labeled 'p'.
- To find the length of the hypotenuse 'p', use the cosine function: cos(θ) = adjacent / hypotenuse.
- Substitute the known values: cos(43°) = 35 / p.
- Rearrange the equation to solve for p: p = 35 / cos(43°).
- Calculate the value: cos(43°) ≈ 0.7314, so p ≈ 35 / 0.7314 ≈ 47.85.
- Round to two decimal places: p ≈ 47.85 m.
