Danny and Rob are amateur storm chasers. The two of them have started an online show where they use trigonometry to locate the storm.

Today, an F3 tornado has touched down. Danny and Rob are on two separate ends of the town and have decided to use triangulation to determine just how far Rob is from the tornado.

The image above depicts the positions of the storm chasers and the tornado. Use trigonometric ratios to determine how far Rob is from the storm.
