Find the area of a triangular pyramid whose base area is 144 in2 and the height is 18 in. 1296 in 3
432 in 3
2592 in 3
864 in 3

1269in2

Step-by-step explanation:

the given values of base b, & height h of triangle in different measurement units between inches (in), feet (ft), meters (m), centimeters (cm) & millimeters (mm). In geometry, A triangle is shape whose three sides are all the same length then it is called as equilateral triangle whereas two of its three sides the same length is called as isosceles. A triangle whose sides are all of different lengths is called as scalene. The formula, solved example & step by step calculations may useful for users to understand how the input values are being used in triangle area calculations. Also this featured calculator uses the various conversion functions to find the triangle area in SI or metric or US customary units.

the circle one

180-142=38 for the acute angle next to the entry

90+38=128

180-128=52

a=52
