<h3>
Answer: A = 43 degrees</h3>
Explanation:
The rule used here is
if sin(A) = cos(B), then A+B = 90.
In this case, B = 47, meaning that,
A+B = 90
A+47 = 90
A = 90-47
A = 43
Therefore,
sin(43) = cos(47)

Answer:16.97cm
Step-by-step explanation:
To find the hypotenuse side of an isosceles of side 12cm each
Using pythagoras theorem
hyp^2=opp^2+adj^2
hyp^2=12^2+12^2
Hyp^2=144+144
hyp=√288
Hyp=16.97cm
