Answer:
1) take the first part of the equation and work it by multiplying (x+2) by 3
3(x+2)+x
3x +6+x
2)put the answer you got into the question you were given
3x + 6+x =2x +16
3)group the x variables and the non x variables
3x +x -2x =16 -6
4) Now work the equation you have
3x+x-2x=16-6
4x-2x=16-6
2x=16-6
2x=10
5) you divide both sides by the x variable
2x=10
2x/2 =10/2
x=5
therefore x is 5
Step-by-step explanation:
Solve for
k
by simplifying both sides of the equation, then isolating the variable.
Exact Form:
k
=
327

Answer:
8
Step-by-step explanation:
since this is a right triangle, we can use trig formulas
cos theta = adj / hyp
cos 37 = x /10
10 cos 37 =x
7.9863551=x
To the nearest integer
8=x
