1) sin(90 - A) = cos A=√(2/3) or √6/3
2) sin²A + cos²A=1
sin²A= 1 -cos²A=1 - (√2/3)²= 1 - 2/3= 1/3
sin A = 1/√3 or √3/3
3) tan A= sin A/ cos A= (1/√3)/(√2/√3)= 1/√2
tan A = 1/√2 or √2/2

Answer:
1) The value of c is given by

2) The value of k is given by

Step-by-step explanation:
Given that function g is defined by
, where c is a constant.
To find c:
Also given that value of g(x) at x=0.5 is equal to -1
ie., 
At x=0.5






Therefore 
2) Given that function h is defined by
, where k is a constant.
To find k:
Also given that value of h(x) at x=20 is equal to 65
ie., 
At x=20



Therefore
