Question

PLEASE HELP!!! Sari stood at a point measured 20 meters away from the base of building A. Turning 40° to building B, she determined that the base

of that building was 25 meters away. How far apart were the buildings? Use a calculator if needed.

Answer 1

x = 16.71m

Explanation:

KL² = KX² + LX² - 2KX × LX × cos(KXL)

x² = 26² + 20² - 2 × 26 × 20 × cos(40°)

x = 16.713m ≈ 16.71m

PLEASE MARK ME AS BRAINLIEST AND HAVE A NICE DAY :)
