Answer:
angels on a line add up to 180.
the angle opposite the 47 degrees is vertically opposite so that angle will be 47 degrees
180 - 47 - 55 = 78
78 + 55 = 133
angle qpu = 133 degrees
I'm not sure what Marc rqt means but hopefully the angles I have worked out help?
Answer: Having your students do speed drills is a way to help them learn quite fast.
Step-by-step explanation:
2 and 3/4=2+3/4
1 and 1/3=1+1/3
2 and 3/4 minus (1 and 1/3)
2+3/4-(1+1/3)
2+3/4-1-1/3
2-1+3/4-1/3
1+3/4-1/3
make bottom number same
3/4-1/3
3/4 times 3/3=9/12
1/3 times 4/4=4/12
3/4-1/2=9/12-4/12=5/12
1+5/12
1 and 5/12
Total = 14 m.
ratio of bows:strips = 3:4
Length for bows = 3/(3+4)*14=6 m
Length for strips = 4/(3+4)*14=8 m
Check: 6m + 8m = 14 m = total, ok.
