Step-by-step explanation:
By definition, complementary angles add to 90 degrees.
The given angle 58 degrees is complementary to 90-58 = 32 degrees. The two angles 58 and 32 add to 90.
Therefore, cos(32) = 0.848 = 0.85
Answer:
does it say like x=_
Step-by-step explanation:
Distance d is directly proportional to time t that he rides.
So d = kt where k is the constant of proportionality
Here k = his speed = 20 mph
So the required equation is d = 20t
7 were in each pack because orginally he had 28 he gave four away. 7*4=28
