Answer:
Cos θ = 13/15
Tan θ= 12/13
Step-by-step explanation:
We are given;
Sin θ = 12/15
From trigonometric ratios, we know that;
Sin θ = opp/hyp
Cos θ = adj/hyp
Tan θ = opp/adj
Thus, since Sin θ = 12/15, then;
Adjacent side = √(15²- 12²)
Adhacent side = √169
Afjacent side =13
Thus;
Cos θ = 13/15
Tan θ= 12/13
Answer:
9
Step-by-step explanation:
- (2^8× 3^−5 ×6^0)^−2× (3^-2/2^3)^4× 2^28=
- 2^-16×3^10×1×3^-8×2^-12×2^28 =
- 2^(-16 -12+28)×3^(10-8) =
- 2^0×3^2 =
- 1×9 = 9
25(6) + [8(6-s)] = t, where s = number of hours and t = total.
If you make it a ratio, it will be 12:6 which is reduced to 2:1.
