Answer:
237.9 meters
Step-by-step explanation:
Let x represent the length of the tunnel.
Applying the Cosine Law, we have:
x² = 201² + 146² - 2*201*146*Cos(85)
x² = 61,717 - 58,692*0.0872
x² = 61,717 - 5,117.9424
x² = 56,599.0576
x = √56,599.0576
x = 237.9 m (nearest tenth)
30 × 30 + 50 × 50 = 3400
square root of 3400 is 58.31 feet.
58.31 feet is the angle of elevation of the kite.
