Answer:
sinx = √2/3
Step-by-step explanation:
cos2x = 1-2sin²x
5/9 = 1-2sin²x
2sin²x =1-5/9
2sin²x = 4/9
sin²x = (4/9)/2
sin²x = (4/9)*(1/2)
sin²x = 2/9
sinx = √2/3
X is 120 degrees, you ask to find the value of y, but there is no y
Answer: The lakes have been a major source for transportation, migration, trade, and fishing, serving as a habitat to many aquatic species in a region with much biodiversity.
Step-by-step explanation:
Look at the numbers so if one half of it is 15 then the other half would be
Answer:
u = 4
v = 18
Step-by-step explanation:
in a parallelogram, diagonals bisect each other into two equal segments so we can do the following:
2u+2 = 5u-10
subtract '2u' from each side to get:
2 = 3u-10
add 10 to each side to get:
12 = 3u
12/3 = u
u = 4
To solve for 'v':
v/3 = 6
multiply each side by 3 to get:
v = 18
