Answer:
The measure of the unknown angle is 15°.
Step-by-step explanation:
Represent this angle by A. Then the complement of A is 90° - A.
"Angle whose complement is five times its measure" would be expressed as
90° - A = 5A
Solve this for A by adding A to both sides:
90° = 6A. Then A = 90°/6, or 15°
If we use the surface of the water as our frame of reference, then Christy's vertical position could be represented by -12 ft.
To make it easier, I am going to simplify it.
4×16-16 ? 4×[24-2×(4+8)]
64-16 ? 4×[24-2×12]
48 ? 4×[24-24]
48 ? 4×[0]
48 ? 4×0
48 ? 0
48>0
The symbol is >, so the answer is A.
Since one kilometer is equal to about 0.621 miles, a runner travels 3.105 miles in a five-kilometer race.
