Answer:
BAC=15
Step-by-step explanation:
angle BOA= 180-30= 150
triangle BAO is
isosceles because it has two equal sides, radii of a circumference so the angles ABO=BAO=(180-150)/2=15
Part A.
4m + 12 + 20m
2 (2m + 6 + 10m)
Part B.
2 (2m + 6 + 10m) = 4(m + 3 + 5m)
4m + 12 + 20m = 4m + 12 + 20m
24m + 12 = 24m + 12
My apologies...but I don't understand what you mean by algebraic properties.
Part C.
Assuming m = 2
4 (m + 3 + 5m)
4 (2 + 3 + 5 × 2)
4 (5 + 10)
4 (15)
60
4m + 12 + 20m
4 (2) + 12 + 20 (2)
8 + 12 + 40
20 + 40
60
Hope this helps!
Use slope 3x and show that 2 slopes are negative reciprocals of each other
I think it’s 15 sorry if I’m wrong
