I think its D. im not positive tho
Answer:Gabrielle is 2*Mikhail:
G = 2M We will use this value for G next
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
G+M = 45 Now in this equation substitute for G, like this:
2M+M = 45
3M = 45 Divide both sides by 3
M = 15 This is Mikhail, and the problem says that:
G = 2(15) = 30
Gabrielle is 30 and Mikhail is 15, and 15+30 = 45 just like the problem says
Step-by-step explanation:
So, all 8 numbers added up would equal 80. and all 6 numbers added up would equal 72. The subtract them. 80-72 is 8. Then divide by 2 because there are 2 numbers. 8/2 is 4. (4 is your answer)
Answer:
Step-by-step explanation:
We can use the identity: 
to simplify this into:
The identity sin(x) = sin(y) --> 
, can be used to simplify this further:
(Add 20 to both sides)
(Add x to both sides)
(Divide both sides by 2)
(Simplify)
If required, we can convert this into radians:
