Question

Archimedes knew that at 7 AM, the sunlight reaches the ground at an angle of 31, degrees. The rock beside which he slept was 5 meters tall.How far from the rock did Archimedes go to sleep?Round your final answer to the nearest hundredth. *

Answer 1

Answer: Archimedes go to sleep at 8.32 metres away from the rock.

Explanation:

Given that the rock beside which he slept was 5 meters tall

Height h = 5m

Angle Ø = 31 degree

To get distance x away from the rock, we will use trigonometry function. SohCahToa

TanØ = opposite/adjacent

Tan 31 = 5/x

x = 5/tan31

x = 8.32m
