This lesson focuses on the geological event of Mt. St. Helens' eruption on May 18, 1980, which dramatically altered its summit. Students will learn how to apply trigonometric principles to determine the new height of the volcano by measuring angles of elevation. By engaging in various 5- and 15-minute check lessons, learners will hone their skills in practical applications of math in real-world geological contexts. Resources include interactive navigation through lesson material.

Add to the assignment • May 18 1980, MT St Helens, erupted with such force it blew off the top. • To determine the new height at the summit a surveyor measured the angle of elevation to the to of the volcano to be 38deg,46’. The surveyor then moved 1000 ft. closer to the valcano and measured the angle of elevation to be 40deg 30’. Determine the new height.
