Answer:
I think it's 1 fourth or .25
Step-by-step explanation:
Answer:
B
Step-by-step explanation:
using the cofunction identity
• sin (90 - x) = cosx / cos(90 - x) = sinx, hence
cos 19° = sin(90 - 19)° = sin 71°
Answer:
(θ) = 84°
Step-by-step explanation:
Given:
sin(θ)=cos(6)
Find:
value of θ
Computation:
sin(θ)=cos(6)
We know that
cos(90-a) = sin(a)
So,
sin(θ)=cos(90-84)
sin(θ)=sin(84)
So,
(θ) = 84°
Train A = 450 tons
Train B = 82 tons.
Since train A is heavier we know the difference already which is 450 so just subtract 532 and 450 to get train B (82 tons)
