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:
meters
Step-by-step explanation:
This is a 45 45 90 triangle. This means that two sides of the triangle are equivalent. In this type of triangle, the two equal sides are represented by 
and the hypotenuse that you are trying to find (u) is represented by 
Therefore, your answer is in simplest radical form.

Answer: a=104
Step-by-step explanation:
104+9=113
Answer:
The number is -2.
Step-by-step explanation:
From the word problem, we can figure out the equation for the unknown number (x).
8x-3=-19
We would then work out the equation to find x.
Add 3 to -19.
8x=-16
Divide -16 by 8.
x=-2
