Let us prove that angle 1 is complementary to angle 3 step by step.
1. We have been given that angle 1 is complementary to angle 2.
2. Since we know that complementary angles add up to 90 degrees, therefore, by the definition of complementary 
.
3. We have been also given that line segment BD bisects 
.
4. By the definition of bisect 
.
5. Angles are congruent if their measures, in degrees, are equal, therefore, by angle congruence postulate 
.
6.
Upon substituting in above equation we will get,
Therefore, by substitution property of equality .
Hence, proven that angle 1 is complementary to angle 3.
diameter is 15 meters then radius is 15/2 = 7.5 meters
so the amplitude is 7.5 m and height will oscillate with amplitude 7.5 m above and below the center.
midline of the oscillation will be 7.5 m
the wheel.take 8 minutes to complete revolution then it means the height will oscillate with a period of 8 minutes
Answer:
2 500 000 rad.
Step-by-step explanation:
Mega is the metric prefix for 
, therefore you just need to multiply by 1 000 000 to find the value in rads.
