In January, the depth of a lake was 878 feet. In August, the depth of the lake was 570.7 feet. What is the percentage decrease of the depth of the lake from January to August?

35% percentage decrease

Step-by-step explanation:

so 570.7/878 is 0.65

which is 65 percent

but we need to know the decrease percentage so

100-65=35

step-by-step explanation:

two pairs of adjacent sides are of equal length. this implies that one diagonal divides the kite into congruent triangles, and so the angles between the two pairs of equal sides are equal in measure. it also implies that the diagonals are perpendicular.
