x = 10
note that sin30° =
since the triangle is right use the sine ratio to find x
sin30° = =
multiply both sides by x
x × = 5 ( multiply both sides by 2 )
x = 10
c. y - 6 = 3(x +2)
the answer to the question is given in point-slope form:
where m = slope and () are a point on the graph.
the first thing to do would be to find slope. you can find slope from two points on a graph by using slope formula:
so, the slope=3. the only equation with a slope of 3 is c. y - 6 = 3(x +2).
you can check your answer by plugging in a given point, for example (0,12) where x = 0 and y = 12:
12 - 6 = 3(0 +2) or 6 = 3(2) or 6 = 6 since it checks out, we know the equation is the right one.
