Sydney applied the steps below to find the product of (3.1)(–1.6).

Step 1: (3.1)(–1.6) = (–1.6)(3.1)
Step 2: = _______________
Step 3: = (–4.8) + (–0.16)
Step 4: = –4.96

Which expression correctly fills in the blank in Step 2?
(1.6)(3) – (1.6)(0.1)
(–1)(3) + (–0.6)(0.1)
(1)(3) – (0.6)(0.1)
(–1.6)(3) + (–1.6)(0.1)

∠x and ∠y are supplementary angles, ∠w and ∠z are a linear pair, and ∠z and ∠y are complementary angles. Then the correct statements are A, B, and E.

Angle is the space between the line or the surface that meets.  And the angle is measured in degree. For complete 1 rotation, the angle is 360 degrees.

Supplementary angle - Two angles are said to be supplementary angles if their sum is 180 degrees.

Corresponding angle - If two lines are parallel then the third line. The corresponding angles are equal angles.

Vertically opposite angle - When two lines intersect, then their opposite angles are equal.

Alternate angle - If two lines are parallel then the third line will make a z-angle and z-angles are equal angles with the parallel lines.

Complementary angle - Two angles are said to be complementary angles if their sum is 90 degrees.

Line l is a straight line. 2 lines intersect line l to form 4 angles.

From the top left, clockwise, the angle is; x, y, z, w.

Angle x and angle y are supplementary angles. This is correct.

Angle w and angle z are a linear pair. This is correct.

Angle w and angle y are adjacent angles. This is incorrect.

Angle x and Angle z are vertical angles. This is incorrect.

Angle z and angle y are complementary angles. This is correct.
