Answer:
Step-by-step explanation:
we have
Line 1
Equation in slope intercept form
The slope is equal to
Line 2
Equation in slope intercept form
The slope is equal to
we know that
If two lines are perpendicular, then their slopes are opposite reciprocal (the product of the slopes is equal to -1)
so
substitute

Choice a
9. The Law of Sines says a:b:c and are the same ratio.
The sines will go in order for acute angles, we have to convert 120 to its supplement 60 and then the order is 29,31,"60" or opposite sides JK, KL, JL
choice b
10.
DEF and FEG are supplments, FEG=180-DEF=180-114=66
DEF and HEG are opposite angles, so congruent HEG=DEF=114
chioce a
The function represents the area of a circle(A) is given by :-
To determine the area of a circle whose radius is 11 inches. , we put the value of r=11 inches, we get
Now, we put in the above function , we get
