A triangle has 3 angles.
The sum of the measures of the angles of a triangle is 180.
In an equilateral triangle, all angles have the same measure.
180/3 = 60
Answer: 60 degrees.
Answer:
Step-by-step explanation:
a) In 1.2 seconds, sound will travel a distance of ...
(1.2 s)(340 m/s) = 408 m
This is the round-trip distance, so the reflecting surface is half that distance away.
The other side of the canyon is 204 m away.
__
b) In 5 seconds, the sound will travel a distance of ...
(5 s)(340 m/s) = 1700 m
This is the one-way distance, so the lightning is about 1700 m away.
