Area = 1/2 bh
96 = 1/2 x b x 8 = 4b
b = 96/4 = 24 inches
Perimeter = 3b [since the other sides are equal to the base]
P = 3 x 24 = 72 inches.
Acute because all angles are less than 90 degrees
Step-by-step explanation:
This problem bothers on the mensuration of solid shapes, prisms.
A prism is a polyhedron, with two parallel faces called bases. The other faces are always parallelograms. The prism is named by the shape of its base.
Here are some types of prisms
Triangular.
Square.
Rectangular.
Pentagonal.
Hexagonal.
Hence in other to solve for the area of any prism we need to know the shape of the prism first
The law of cosines is used for this purpose. It tells you
c² = a² + b² - 2ab×cos(C)
Solving for the angle C gives
C = arccos((a² + b² - c²)/(2ab))
C = arccos(( 17² + 15² - 19²)/(2×17×15))
C = arccos(153/510)
C ≈ 72.5424°
The measure of the angle opposite the longest side is about 73°.
