Scientist can measure the depths of crayers on the moon by looking at pictures of the shadows. the length of the shadow cast by edge is 500 meters. the angle of elevation of the rays of the Sun is 55 degrees estimate the depth of the crater

Explanation:

Tita:

depth of the crater: d= ?

length of the shadow cast by edge:

i think it because equal matrices have equal dimensions, only square matrices can be symmetric. for all indices and . every square diagonal matrix is symmetric, since all off-diagonal elements are zero. in linear algebra, a real symmetric matrix represents a self-adjoint operator over a real inner product space.
