Answer: 18080!

Step-by-step explanation:400 x 450

1. Multiplying from the oneths place ( turning 45.2 into 450)

2x0=0 2x0=0 2x4=8 = So the first answer is 800

2. Multiply from the tenths place

5 x 0 = 0 5 x 0 = 0 5 x 4 = 20 = the second answer is 2000

Multiplying the hundredths place

4 x 0 = 0 4 x 0 = 0 4 x 4 = 16 = The third answer is 1600

800 + 2000 + 1600 = 18080 Hope this helped! :)

If angle 3 and angle 4 are corresponding angles, then their vertical angles are also corresponding angles

<h3>Answer: Always</h3>

Explanation:

Drawing out a diagram usually helps with these types of problem. See the diagram below.

We have angle 3 and angle 4 as corresponding angles (since they are both in the north east corner of each four-corner configuration). Angle 1 = angle 3 is one pair of vertical angles and angle 2 = angle 4 is another pair of vertical angles. We see that angles 1 and 2 are corresponding angles in the south west corners of each four-corner configuration. That's why the original statement is always true.
