<span>Let the height of the tree be h foot.
Trigonometric ratio for tangent = Opposite side / adjacent side----(1)
Since the tree is standing vertically on a level ground, the three points, [ Top of the tree, the point where the tree touches the ground and the point where the shadow ends] form a right angled triangle.
Applying (1) for the above three points, tan(24.7)=(height of the tree)/(length of shadow)
Hence, height of the tree = tan(24.7)*(length of the shadow)
= (0.46)*140
= 65 foot (Rounding off to the nearest foot)</span>
He sold 76 shirts and 24 pants.
Step-by-step explanation:
Given,
Cost of one t-shirt = $20
Cost of one pants = $45
Total items sold = 100
Total sales = 2600
Let,
x be the number of t-shirts
y be the number of pants
According to given statement;
x+y=100 Eqn 1
20x+45y=2600 Eqn 2
Multiplying Eqn 1 by 20
Subtracting Eqn 3 from Eqn 2
Dividing both sides by 25
Putting in Eqn 1
He sold 76 shirts and 24 pants.

Answer:
18.18% error
Step-by-step explanation:
Use the percent error formula,
% error = | (measured - accepted) / accepted | x 100
Plug in the values we know:
% error = | (180 - 220) / 220 | x 100
% error = | - 0.18 | x 100
% error = 18.18% error
No, it means that she will pay 296 plus 11% of 296.
solve: 296 + 32.56= 328.56 altogether of her bill.
