From the law of sines, we have
where 
is the leg we're interested in, 
is the hypothenuse, 
is the angle opposite to , and 
is the angle between and .
So, in the first case, we can use
And in the second excercise, we use
Answer:
7/1 or 7
Step-by-step explanation:
because you rise (vertically) seven and run (horizontally) 1, so 7/1 but simplified it's just 7 so either is valid.
Answer:
Step-by-step explanation:
(a) the co-ordinates of the point where the line crosses the y-axis,
y intercept occurs when x = 0
y = 5 - 2(0)
y = 5
(0, 5)
(b) the gradient of the line,
the general line formula is y = mx + b, where m is the slope and b is the y intercept.
y = 5 - 2x
y = -2x + 5
m = -2
(c) the equation of a line parallel to L.
Parallel lines have the same slope, but different y intercepts.
The simplest parallel line formula is
y = -2x + 0
y = -2x
