Answer:
<em>0° and 18°</em>
Step-by-step explanation:
3tan²β - tanβ = 0
tanβ(3tanβ - 1) = 0
tan β = 0 ⇒ 
<em>= 0°</em>
3tan β - 1 = 0 ⇒ tan β = 
⇒ 
= arctan ( ) ≈<em> 18°</em>
Alright, so in order to solve this, we need to isolate the variable. So, we need to simplify the equation. So, we have the equation:
82•P = 84
So, we need to divide both sides by 82 because it is the opposite of multiplication. So, we have :
82•P/82 = 84/82
So, 82•P/82 = 1p = P.
84/82 = P
If You Need Decimal Form,
84/82 = About 1.02
Answer:
0
Step-by-step explanation:
Theres different ways you can solve this but the way I did it both sides were equal to eachother.
Answer:
Micheal sent 40 messages, Christine sent 20, and Dave sent 11.
Step-by-step explanation:
Christine, Dale, and Michael sent a total of 71 messages
C + D + M = 71
Dale sent 9 fewer messages than Christine
D = C - 9
Michael sent 2 times as many messages as Christine
M = 2C
Plug-in the numbers.
C + C - 9 + 2C = 71
4C - 9 = 71
4C = 80
C = 20
Now, plug in to other equations for other results.
D = (20) - 9
D = 11
M = 2(20)
M = 40
Micheal sent 40 messages, Christine sent 20, and Dave sent 11.
Verify?
40 + 20 + 11 = 71.
