Answer:
124°
Step-by-step explanation:
cos X = (11²+7²-16²)/2(11)(7)
= (121+49-256)/154
= -86/154
= -0.5584
X = cos~¹ -0.5584 = 124°
Using up is the y value (increasing) and left is the x value (decreasing).
(6-3,-5+7)
(3,2) is the new point

<span>15 - 1/6n = 1/6n - 1
rewrite
1/6n - 1 = 15 - 1/6n
add 1/6 n to both sides
1/6n - 1 + 1/6n = 15 </span>- 1/6n + 1/6n
Simplify
2/6n - 1 = 15
1/3n - 1 = 15
add 1 to both sides
1/3n - 1 + 1 = 15 +1
1/3n = 16
Multiply 3 to both sides
1/3n * 3 = 16 *3
3/3n = 48
n = 48
Answer:
Step-by-step explanation:
Ax+By=C (remember this formula)
-2/9x+2=y (switched sides to make it easier)
-2x/9+2-y=0 ( put y on the other side)
-2x/9-y=-2 ( put 2 on the other side)
So a must be positive so multiply by -1
2x/9+y=2
answer
2x+9y=18 (LCM)
