Mr. jones
Step-by-step explanation:
6/7 is 85.71% which is greater than 83%.
Answer:
length = 4x
width = 3x
perimeter = 56 m
also, perimeter = 2 (length + width) [from formula]
therefore, 2(4x + 3x) = 56m
2(7x) = 56m
14x = 56m
x = 56/14 m
x = 4m
45°?
Step-by-step explanation:
The second floor of a building is 20 m above the ground.
From this floor, the angle of
elevation of the top of an eucalyptus tree is 15°
and the angle of depression of the foot of the same tree is 10°
10+15+20=45
