Answer:
3
Step-by-step explanation:
The bird flew 5.45m far from the tree.
Step-by-step explanation:
Given,
Sin70° = 0.94
Cos70° = 0.34
Angle of flight = 70°
Refer the diagram attached for better understanding.
Cos70° = (adjacent side) / (hypotenuse)
0.34 = 2/ hyp
hyp = 2/(0.34)
hyp = 5.8 m
We have to find the opposite side of the angle of flight for the distance the bird flew.
Sin70° = (opposite side) /(hypotenuse)
0.94 = (opposite side) / 5.8
Opposite side= 0.94 x 5.8
= 5.45m
The bird flew 5.45m away from the tree to another tree.
Answer:
Why is it not necessary to line up the decimal point to multiply?
- In addition and subtraction, it is important to line up the place value columns because we can only add or subtract digits in the same place value columns.

Answer: false
Step-by-step explanation:
false because 19 - 6 =13 and 13 +12 = 25 and 25 - 18 = 7
