The length of the ladder is 34.33 feet if the electrician leans an extension ladder against the outside wall of a house so that it reaches an electric box 33 feet up. The ladder makes an angle of 74° with the ground.
<h3>What is a right-angle triangle?</h3>
It is defined as a triangle in which one angle is 90 degrees and the other two angles are acute angles. In a right-angled triangle, the name of the sides are hypotenuse, perpendicular, and base.
We have:
An electrician leans an extension ladder against the outside wall of a
house so that it reaches an electric box 33 feet up. The ladder makes
an angle of 74° with the ground.
The ladder, wall, and ground makes a right angle triangle.
From the sin ratio;
Here is X is the length of the ladder.
We know sin74 = 0.961
After putting, we will get:
X = 34.329 ≈ 34.33 feet
Thus, the length of the ladder is 34.33 feet if the electrician leans an extension ladder against the outside wall of a house so that it reaches an electric box 33 feet up. The ladder makes an angle of 74° with the ground.

Well, first, you would fine how much she put in the bank in the first place!
250,000-96,000=154,000
Then you would do 154,000*0.02 to find how much interest is charged per month.
154,000*0.02=3080
Finally, you would multiply 3080 by 6 {because you need to account for all of the months}.
3080*6=18,480

Answer: correct option is A
0.100
Step-by-step explanation:
Given that
population = 500 elements.
To draw a simple random sample of 50 elements from this population. On the first selection
The probability = 50/500 = 0.1
The probability of an element being selected is 0.100
Time=(distance)/(speed)
speed=55 mi/hr
Total distance=440 miles
Distance covered=275 miles
remaining distance=440-275=165 miles
Time taken to cover the remaining distance will be:
time=165/55=3 hours
Total time taken to travel=440/55=8 hours
if we are to use the equation given by:
55h+275=440
time taken will be found by solving for h, thus we shall have:
55h=440-275
55h=165
h=165/55
h=3 hours
Answer: 3 hours
Start by multiply by sqrt2 / sqrt2
= 8 sqrt2 - 3*2
