Use difference quotients with δx = 0.1 and δy = 0.1 to estimate fx(1, 7) and fy(1, 7). (round your answer to four decimal places.) f(x, y) = e−x sin y fx(1, 7) = -0.0448 fy(1, 7) = then give better estimates by using δx = 0.01 and δy = 0.01. (round your answer to four decimal places.)

]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
