What is the surface area of this square pyramid? Round your answer to the nearest tenth, if necessary. 43.8 yd² 66.6 yd² 105 yd² 171.6 yd² Note: Image not drawn to scale. The figure shows a square pyramid. The slant height is shown as a dashed line segment perpendicular to the base edge. The length of the base edge is 6.2 yard. The lateral edge makes a 60 degree angle with the base edge.

good luck on your studies! : )

step-by-step explanation:

assume that you have 3 different side lengths.   apply the pythagorean theorem here:   square each of the two shortest sides; call them a and b, so that their squares are a² and b².   also square the longest side, calling the result c².

now, if a² + b² = c² is true, the triangle is a right triangle; otherwise it is not a right triangle.
