Answer:
yes it is less then a right angle
Step-by-step explanation:
The first is a right triangle because there is a right angle, and it is scalene because none of the sides are congruent.
The second is an obtuse triangle because there is an obtuse angle, and it is an isosceles triangle because two of the sides are congruent.
The third is an acute triangle because all of the angles are acute, and it is an <span>isosceles triangle because two of the sides are congruent.
The fourth is a right triangle because it has a right angle, and it is a s</span><span>calene because none of the sides are congruent.</span>
Answer: 25 in³
Step-by-step explanation:
We can calculate the volume of the pyramid by first calculating the volume of a prism with the same dimensions, and then dividing by 3 (all pyramids a volume that's of the volume of a prism with the same dimensions).
The volume of a prism is its base area times its height. The base would be a square, so its area is 5², which is 25. The height is 3 inches, making the prism's volume 75 in³.
The volume of the pyramid would be one-third of this value, which is 75 which is 25 in³.
