It would most likely equal to 6. Hope this helped.
Step-by-step explanation:
Answer:
Part A:
given that cos β = 3/5
that means the base line is 3 and the hypotenuse is 5
Note that, The base line 3 is adjacent to β and opposite to α.
Sin α = opposite / adjacent
sin α = 3 /5
Part B:
α and β are complementary angles
Answer:
8 hours
Step-by-step explanation:
The time required is the temperature difference divided by the rate of change of temperature:
(-54 -42)°F/(-12 °F/h) = -96/-12 h = 8 h
Answer:
Make x 0 and y 3
Step-by-step explanation:
0 multiplied by 2 is 0
-3 multiplied by 3 is -9
0-9 = -9
Answer:
-1/2
Step-by-step explanation:
cos(x+pi) = -cos(x), so the answer is -1/2.
