Jack has a 35-foot ladder leaning against the side of his house. If the bottom of the ladder is 21 feet away from his house, how many feet above the ground does the ladder touch the house?
Answers
Answer:
The distance above the ground does the ladder touch the house x = 28 ft
Step-by-step explanation:
Given data
Length of the ladder = AC = 35 ft
BC = 21 ft
AB = x = distance above the ground does the ladder touch the house
From Δ ABC
x = 28 ft
Therefore the distance above the ground does the ladder touch the house is x = 28 ft
Answer: the answer would be 28 ft

Answer:
88%
Step-by-step explanation:
22/25 = .88 x 100= 88%
Answer:
88%
Step-by-step explanation:
First, you start with the bottom (denominator). You turn it into 100 since all percentages are over 100. So 25 times 4 is 100. Therefore, you also have to multiply the top with a 4, getting an 88 over 100. That is equal to 88%.

If both non right angles are 45° we have an isosceles right triangle and AC is also 19 feet.
So now we can use the Pythagorean theorem to find the missing side.
a² + b² = c² and we are looking for BC - the hypotenuse of the triangle
19² +19² = c² 361+361 = c² 722= c² and c=√722 or about 26.87
Final answer:
In triangle ABC, if angle A is a right angle and angle B is 45 degrees, it is a 45-45-90 special right triangle. Given that AB = 19 feet, BC will also be 19 feet due to the properties of 45-45-90 triangles.
Explanation:
In triangle ABC, since angle A is a right angle and angle B is 45 degrees, we are dealing with a 45-45-90 triangle which is a special right triangle. In a 45-45-90 triangle, the sides are in the ratio of 1:1:√2.
Given that AB = 19 feet, because of the special properties of a 45-45-90 triangle, we know that in these triangles, the two legs are of equal length. So the length of BC, which is the other leg of the triangle will also be 19 feet.
