Answer:
Equilateral triangles are always acute triangles.
Scalene triangles are sometimes acute triangles.
Right triangles are never acute triangles.
Obtuse triangles are sometimes isosceles triangles.
Step-by-step explanation:
Equilateral triangles are always acute because each angle is 60⁰.
Scalene triangles have sides that are different lengths. They can be right, obtuse, or acute.
A right triangle is never acute because it has a 90⁰ angle. Acute means all angles are less than 90⁰.
An obtuse triangle can be either scalene or isosceles. It always has one angle greater than 90⁰ (obtuse).
Answer:
The answer is 1120m if its asking for the vollume but if its and area of the flat surface its 140m
Step-by-step explanation:
14 time 10 = 140 for flat surface
14 times 10 times 8 is 1120 for vollume
There is no sum for this geometric series. it diverges rather than converges due to the absolute value of the common ratio (r), which is -3, being 3. for a geometric series to have a sum (to converge), the absolute value of r must be less than 1.
(you find r by dividing a2/a1, a3/a2, etc.)
hope this helps
Answer:
Step-by-step explanation:
Remark
This is a right angle triangle.
Proof
a^2 + b^2 = c^2
a = 3
b = 4
c = 5
3^2 + 4^2 = 5^2
9 + 16 = ? 25
25 = 25
Area
The 2 smaller legs are perpendicular to each other.
Area = 1/2 a * b
Area = 1/2 * 3 * 4
Area = 6
