Kyung is building a triangular pool in his backyard. he knows that side f is 12 m and that both angles g and f are 40°, which means that angle d is 100°. what is the length of side d? round the answer to the nearest tenth.

Each of the walls of a room with square dimensions has been built with two pieces of sheetrock, a smaller one and a larger one. the length of all the smaller ones is the same and is stored in the variable small. similarly, the length of all the larger ones is the same and is stored in the variable large. write a single expression whose value is the total area of this room. do not use any method invocations.

Witch represents the inverse of the function f(x)=1/4x-12
