Z varies directly as x and inversely as y. If z = 9 when x = 63 and y = 7, find z when
x = 28 and y= 4.

Me complete this proof! prove that a quadrilateral is a square. me with the steps for this proof.

]supplementary angles are two angles that add up to . • complementary angles are two angles that add up to degrees. • adjacent angles share a and a • congruent angles have the measure. • an triangle has one angle that is greater than 90 degrees. • a triangle with angles 45°, 45°, and 90° would be a triangle
