The Pythagorean theorem can be used for this.
.. (tip distance)² = (shadow length)² + (tree height)²
.. tree height = √((tip distance)² -(shadow length)²)
.. tree height = √((60 ft)² -(40 ft)²) = √(2000 ft²)
.. tree height ≈ 44.72 ft
Answer:
Step-by-step explanation:
Answer:
Isosceles and obtuse
Step-by-step explanation:
It is not a scalene triangle because it has two same lengths 41 degrees and 41 degrees.
<u>It is a </u>Isosceles triangle because two of the sides have the same lengths 41 degrees and 41 degrees
<u>It is an</u> obtuse triangle because it has on obtuse angle which is 98 and two acute angles that are 41 degrees
It is not an equilateral because not all of the sides are the same lengths
It is not a right triangle because there are 90 degree angles
It is not an acute triangle because not all the angles are acute angles
