A) 13 degrees because it would be 90-77
If two angles are complementary, then the two angles add up to 90 degrees.
If angle A is 77, then the complement would be 90-77 or 13 degrees.
b) The complement of the complement of the angle is the angle itself.
Say the angle A is 30 degrees. It's complement is 90-30 or 60 degrees.
The complement of the 60 degrees is 30 degrees.
So the complement of the complement of the angle would be the angle itself.
Hope this helps :)
Answer:
A: 3,655 Meters
Step-by-step explanation:
Beach =436=> Hotel =3,219=> Restaurant. Your problem is Beach =?=> Restaurant, so you just add the two values. 436+3,219=3,655.
Answer:
Step-by-step explanation:
Initial Quantity of salt Q(0) = 100 kg
Capacity of tank = 1000 L
Inflow of liquid = 10 l /minute and outflow = same rate thus leaving the content of volume 1000 L at any time
Assume after entering constantly mixes and drains out.
Concentration flow = inflow - outflow
= 0.05(10) - 
i.e. 
, Q(0) = 100
Use Q(0) = 5
-45 = A
So the equation would be
a) Initial concentratin = 
b) Use the solution fo rDE substitute t =1
Q(1) = 50-45e^(-0.01) = 5.4477 kg
c) As t becomes large Q = 50
So concentration limit = 50/1000 = 0.05
Answer:
y = 27
Step-by-step explanation:
line segment BA and CD are congruent, turn them into an equation
3y - 59 = y - 5
subtract 1y from both sides, you get 2y - 59 = -5
then, add 59 to both sides and the equation is now 2y = 54
divide each side by 2 and you get the value of y (y = 27)
