Answer:
a 44°
Step-by-step explanation:
Think of the right triangle formed by the beam, the ground, and the wall.
The beam is the hypotenuse. For the angle between the ground and the beam, call it angle A, the 13.9 ft side is the opposite leg. The trig ratio that relates the opposite leg and the hypotenuse is the sine.
sin A = opp/hyp
sin A = 13.9/20
sin A = 0.695
A = sin^-1 0.695
A = 44°
1st day: 7 bushes. Every next day Omar was clearing 3 more than he did day before.
2nd day:10 bushes
3rd day:3 more bushes than 2nd day so 6 more bushes. 10+6=16 bushes
4th day: 3 more bushes than 3rd day so 9 more bushes. 16+9=25 bushes
5th day: 9+3=12. 25+12=37 bushes.
6th day: 12+3=15. 37+15=52 bushes.
7th day: 15+3=18. 52+18=70 bushes
8th day: 18+3=21. 70+21=91 bushes cleared till 8th day.
9th day: 21+3=24. 91+24=115 bushes.
10th day: 24+3=27. 115+27=142
Omar needed 10 days to clear 140 bushes.
Answer: 2
This question is asking you to divide 20 by 10. This means:
20 ÷ 10=2
If 10 can go into a number 2 times, it means that 10•2=20. So, since we dont know how many times 10 goes into 20, we divide 20 by 10.
Below I have attached an image of the long division in case you need to do that as well.
Hope this helps comment below for more questions :)
