Answer:28
Step-by-step explanation:
Mowing 50
Car washing 34
Total amount 84
Now divide by 3 accounts 84/3=28
Answer:
1st angle will 60degree =90-60,. 1nd angle =60 degree.vertically opposite angle,
all u are doing is adding them up
To determine if a line is perpendicular to another, you must first determine the slope...
m = y1-y2/x1-x2
m of FK = 3-5/3-6 = -2/-3 = 2/3
m of FJ = 3-2/3-8 = 1/-5
m of FL = 3-0/3-5 = 3/-2
m of KJ = 5-2/6-8 = 3/-2
m of KL = 5-0/6-5 = 5
m of JL = 2-0/ 8-5 = 2/3
In order for two lines to be perpendicular, their slopes must be opposite reciprocals...
FK is perpendicular to FL
FK is perpendicular to KJ
JL is perpendicular to FL
JL is perpendicular to KJ
FJ is perpendicular to KL
I believe the slope is 3/4
9-3 = 6
4 - (-4) = 8
Simplify to get 3/4
