In ΔDEF, e = 130 inches, f = 130 inches and ∠D=57°. Find the area of ΔDEF, to the nearest square inch.
Question
Solution 1
To find the area of a triangle given two sides and the included angle, you can use the formula:
Area = 1/2 * a * b * sin(C)
In this case, a and b are the lengths of the sides (e and f), and C is the included angle (∠D).
So,
Area = 1/2 * e * f * sin(∠D) = 1/2 * 130 inches * 130 inches * si Knowee AI StudyGPT is a powerful AI-powered study tool designed to help you to solve study prob
