Answer:
line FG
Step-by-step Explanation:
In the diagram, line CD passes through
The slope of this line is found using the formula,
We substitute the values to get,
So line CD is the line with slope
From the graph we can see clearly that, the only line that is perpendicular to CD is line FG.
Line FG also passes through
We can verify that the product of these two slopes is negative 1.
Therefore the correct answer is C

Answer:
Below in bold.
Step-by-step explanation:
sin 66.4 = opposite side / hypotenuse
sin 66.4 = 21.3 / y
y = 21.3 / sin 66.4
y = 23.24.
tan 66.4 = 21.3 / x
x = 21.3 / tan 66.4
x = 9.31.
