127.8. (12.2 =146 sq inches. 10.6 = 126 square inches. 146x126=18,396 square inches. 18,396/144 (144 square inches in a square foot) is 127.75 square feet).
Answer:
The ladder is not safe at this height. The height from ground to top of the ladder is < 11.6 ft for safety reasons and this can be determined by using trigonometry functions.
Step-by-step explanation:
The ladder is not safe at this height. The height from ground to top of the ladder is < 11.6 ft for safety reasons and this can be determined by using trigonometry functions.
Given :
Joshua has a ladder that is 12 ft long.
He wants to lean the ladder against a vertical wall so that the top of the ladder is 11.8 ft above the ground.
For safety reasons, he wants the angle the ladder makes with the ground to be no greater than 75°.
Check the angle that the ladder makes with the ground:
The ladder is safe when the angle the ladder makes with the ground to be no greater than 75° but is so, the ladder won't be safe.
To make the ladder safe, the height should not be 11.8ft.
The height from ground to top of the ladder is < 11.6 ft for safety reasons.
The length of the minor arc AB is 6.3cm
To find a percentage, if I am ready your question correctly, would be as simple as dividing the number by 100. For example, finding the percentage of 73.
73/100 = .73%
You could also just move the decimal place over two spots to the left.
