The sine of an angle is equal to the cosine of the complementary angle.
That is; sin r = cos 90 -r , where r is an acute angle
Therefore;
sin 73 = cos (90-73)
sin 73 = cos 17
Hence the value of r = 17

Answer:
1) B. n ≥ 3
2)A. 5x – 9
Step-by-step explanation:
1)
If the least value of n is 3 then all the values of n must be greater or equal to 3
Thus the correct option is B :n ≥ 3
2)
Given:
Milo's age is 9 years less than 5 times Pearl's age
Pearl's age is x years
5 times Pearl's age= 5x
then milo's age= 5x-9
so the correct option is A. 5x – 9 !
