Answer:

Step-by-step explanation:

Opposite = BC ,
Adjacent = AB = x = 3 ,
Hypotenuse = AC = y = 22
<em><u>Using trigonometric ratios.</u></em>

Since we have adjacent and hypotenuse we use cosine's ratio
to find the angle.

Answer:

Step-by-step explanation:





Since the given line is <span>ll to the req. line, so
</span>x-2y=62y = x - 6
y = (1/2)x - 3
slope = 1/2
equation of the req. line is
y - y1 = m(x - x1)
y - 6 = 1/2(x - 1)
2(y - 6) = 1(x - 1)
2y - 12 = x - 1
2y = x -1 + 12
2y = x + 11
y = (1/2)x + 11/2
