(2x+40)+(3x+20)=180
because they are supplementary angles
therefore:
2x+3x+40+20=180
5x+60=180
5x=120
x=24

Cos (x+y)/cos x sin y
= cos x cos y - sin x sin y / cos x sin y
= cos x cos y/cos x sin y - sin x sin y / cos x sin y

Answer:
t/7
Step-by-step explanation:
Since the ratio between the amount of water and the time should be the same, 84/12 = 7.
Hence, the ratio is t/7.
Hope this helped!
Answer:
Step-by-step explanation:
sin A = 5/13
sin B = 12/13
cos A = 12/13
cos B = 5/13
tan A = 12/5
tan B = 5/12
