Answer:

Always

Step-by-step explanation:

The definition of a perpendicular line is that it intersects another at a 90 degree angle. Using this, by verticals, the opposite corner angle must also be 90-degrees, and since one side of a line is 180 degrees, 180-90 = 90, which ensure the rest of the angles will be 90 degrees too.

Answer:

<h2>120 Pennies</h2>

Step-by-step explanation:

First, we need to find 80% of 400

400 x 0.8 = 320

Now 50% of 400 is 200

320 - 200 = 120
