Answer:
Step-by-step explanation:
To find the length of the pole, use Pythagorean theorem,
4.6m = 4.6*100 = 460 cm
hypotenuse² = base² + altitude²
altitude² = hypotenuse² - base²
=460² - 280²
= 211600 - 78400
= 133200
altitude = √133200 = 364.97 cm
Length of the pole = 364.97 cm
b) Length of stair² = 95² + 364*94²
= 9025 + 133200
= 142225
Length of stair= √14225 = 377.13
Length of stair = 377.13 cm
