Ratio of 2 complementary angles = 4:5
Let first angle be 4x
Let second angle be 5x
Sum of two complementary angles = 90
4x + 5x = 90
9x = 90
x = 90/9 = 10
First angle = 4x = 4*10 = 40
Second angle = 5x = 5*10 = 50
I hope it is helpful...
20 miles per hour. all u have to do is divide 50 by 2.5 and u get your unit rate 20
