Suppose a triangular silk scarf has both of its shortest sides 14 inches long. If the angle between these sides is 110º, what is the area of the scarf? Round your answer to the nearest tenth of a square inch. (Enter only the number.)

Answer 1

if the third side is 2x, then

x = 14 sin 55º, and the height is
h = 14 cos 55º,

so the area is hx = (14 cos55º)(14 sin55º) = 7 sin 110º
