False because you can only use the Pyth. Theorem on right triangles which may not necessarily be ALL similar triangles.
D because they played for two days so that makes you multiply the number of seconds by the same number
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°
we know that
The internal angles of the triangle
are
Angles



The internal angles of the triangle
are

therefore
the answer is
