A triangle has 180 degrees
180-25=155
15+16=31
155/31=5
15*5=75
16*5=80
The two angles are 75 degrees and 80 degrees.
50 km/h = 50,000m / hr
= 50,000 / 60 = 833.333 m / minute
The tire rotates 500 times for this period
So the circumference of the tire = 833.333 / 500 m
= 1.67 m to the nearest hundredth
=
The answer is 0. Even thought the second number has an extra zero at the end, they are the same value.
