Question. A snail is at the bottom of a well 30 feet deep. It crawls up 3 feet each day, but at night it slips down 2 feet. How long will it take for the snail to crawl out of the well?

Die Antwort ist tatsächlich 28 Stunden. Warum? Die Logik ist wahr, 1 Fuß pro Stunde für beispielsweise 27 Stunden / Fuß. Am Ende der 28. Stunde klettert die Schnecke 3 Fuß (30 Fuß) und erreicht die Spitze, bevor sie diesmal nicht zurückrutscht .

Translation: The answer is actually 28 hours. Why? The logic is true, 1 foot an hour for, let's say, 27 hours/feet, then at the end of the 28th hour the snail climbs 3 feet (making 30 feet,) and reaches the top before, this time, not sliding back.

answer: 40.95

step-by-step explanation:

1. 180°. the sum of the interior angles of a triangle is 180°, for the equilateral triangle that it has three equals side is 60°+60°+60°=180°.

2. 60°. each interior angle of a equilateral triangle is 60°

3. 120°. the measure of ∠m is 120°, the sum of the angles ∠m and ∠n is equal to 180°. so, in order to find the measure of ∠m, we have ∠m+∠n=180° > ∠m=180°-∠n > ∠m=180°-60°=120°.

4. 360°. the sum of the exterior angles of an equilateral triangle is ∠m+∠r+∠x=120°+120°+120°=360°. the exterior angles of any triangle always add 360°.
