Answers:
∠A=45° & ∠B=45°
Step-by-step explanation:
In triangle ABC, all angles are less than 180° but their sum is 180°
For the trigonometric statements
sin(A)=cos(B)
sin(B)=cos(A)
These are true when these angles that are A and B are equal and on these angles the sin and cos value must be same.
Hence, both angles are of 45°
Alternatively, recall that if
, then
, and so
Take
, so that
, and we have the original limit. So the limit is equivalent to the value of
, i.e.
Answer:
about what
Step-by-step explanation:
3/5 of 60
= 60 divided by 5
= 12
12 x 3
