Step-by-step explanation:

From the question, we are informed that the trail that Brandon is hiking is 4.2 miles long, and Brandon plans to stop for Lunch after he completes 1.6 miles.

The expression represents the remaining distance Brandon needs to hike will be gotten by subtracting 1.6 miles from 4.2 miles. This will be:

= 4.2 - 1.6

= 2.6 miles

according to the triangle sum theorem, all the angles in a triangle must add up to 180 degrees. if we know one angle is already 90, we do 180-90=90. the other 2 angles must add up to 90, exactly.

the answer is 62.8 cubic units
