Answer:
Sin A = 0.38462
Step-by-step explanation:
From the trigonometric function,
Sin A = ................... 1
So that, applying the Pythagoras theorem to determine the value of hypotenuse,
=
+
= +
= 576 + 100
= 676
Hyp =
= 26
The hypotenuse of the triangle is 26.
Thus, from equation 1;
Sin A =
Sin A = 0.38462
Answer:
liked = 45 ; disliked = 18
Step-by-step explanation:
Let the number of songs he liked be x & disliked be y.
The ratio of x & y :-
And total number of songs he listened = 63
Then, x + y = 63...................eqn.1
=> x = 63 - y
Substituting the value of x in eqn. 2x = 5y gives :-
2(63 - y) = 5y
=> 126 - 2y = 5y
=> 7y = 126
=> y = 18
Substituting the value of y in eqn.1 gives
x = 63 - 18
= 45
Hence no. of songs he liked = 45 & disliked = 18
