Answer:
±5sqrt(2) =x
Step-by-step explanation:
65=15+x^2
Subtract 15 from each side
65-15=15-15+x^2
50 = x^2
Take the square root of each side
±sqrt(50) = sqrt(x^2)
±sqrt(25*2) =x
±sqrt(25)sqrt(2) =x
±5sqrt(2) =x
17-2V=41
subtract 17 from both sides
-2v =24
v = 24 / -2 = -12
v=-12
(x + 1)·(x + 1 + 11) = (x + 4)·(x + 4 + 1) --> x = 2

Answer:
67°
Step-by-step explanation:
Angles on a straight line add to 180, so:
A + D = 180
D = 180 - A
D = 180 - 113
D = 67
