Answer:
1st one
Step-by-step explanation:
1) sin(90 - A) = cos A=√(2/3) or √6/3
2) sin²A + cos²A=1
sin²A= 1 -cos²A=1 - (√2/3)²= 1 - 2/3= 1/3
sin A = 1/√3 or √3/3
3) tan A= sin A/ cos A= (1/√3)/(√2/√3)= 1/√2
tan A = 1/√2 or √2/2
Answer:
-3x - 7y = 36
Step-by-step explanation:
The given line -3x - 7y = 10 has an infinite number of parallel lines, all of the form -3x - 7y = C.
If we want the equation of a line parallel to -3x - 7y = 10 that passes through (-5, -3), we substitute -5 for x in -3x - 7y = 10 and substitute -3 for y in -3x - 7y = 10:
-3(-5) - 7(-3) = C, or
15 + 21 = C, or C = 36
Then the desired equation is -3x - 7y = 36.
Answer:
There is 9 on each pace and 3 on a row
Step-by-step explanation:
54/6=9
if there is 9 on each side and the same on each side, then it has to be 3 in each row and column. Also, this is a Rubix cube
