Step-by-step explanation:
Given
tan a =
= 
We require the hypotenuse h
Using Pythagoras' identity
h² = 9² + 40² = 81 + 1600 = 1681 ( take square root of both sides )
h =
= 41 , thus
sin a =
= 
cos a =
= 
Answer:
a)c
Step-by-step explanation:
i dunno about b
10. If it rained 7/10 of the days, 3/10 days did not receive rain.
90 days multiplied by 3/10 is 27.
It would not rain about 27 days in the 90 days.
11. x multiplied by 8 and a half equals 5.
(8 and 1/2)x = 5
x = .588235 which is about 6/10
12. C = 6/10 and D = 8/10 so the product would be 48/100 which is close to 5/10. This point is N.
