A right triangle has a leg B of length 7 and a hypotenuse of length 11. What is the length of the other leg A? Round to the nearest tenth, if necessary.
A. 2.0
B. 8.5
C. 13.0
D. 9.6
Please help, I was gone for this lesson, just need someone to explain how they got the answer.
@Heyo Is not 100%. sucks that I was the first person to test that, but I will tell you guys what 100% should look like.
1. 8.5
2. 9.4
3. (1, 1)
4. -2
5. 4/3
6. -2
7. y = 2x - 5
8. 30
9. y =2/3 + 9
This is 100% for Connexus!
as you know
a^2 + b^2 = c^2
so, plug in your numbers
7^2 + b^2 = 11^2
49+b^2 = 121
b^2 = 72
b = √72 = 8.5
find the perimeter of the shape below
do yall know the other ones
To find the length of the other leg A of the right triangle, we can use the Pythagorean theorem. The Pythagorean theorem states that in a right triangle, the square of the length of the hypotenuse (c) is equal to the sum of the squares of the lengths of the legs (a and b).
In this case, we are given the length of one leg (b = 7) and the length of the hypotenuse (c = 11). Let's represent the unknown length of the other leg as a.
Using the Pythagorean theorem, we can set up the following equation:
a^2 + 7^2 = 11^2
Simplifying, we have:
a^2 + 49 = 121
Subtracting 49 from both sides, we get:
a^2 = 72
To solve for a, we need to take the square root of both sides, giving us:
a ≈ √72
Now we can evaluate the square root of 72. Since 8 squared (8^2) is 64, and 9 squared (9^2) is 81, the square root of 72 lies somewhere between 8 and 9.
To find a more accurate answer, we can estimate the value of the square root of 72 to the nearest tenth. Taking the square root of 72 on a calculator, we find that it is approximately 8.5.
Therefore, the length of the other leg A of the right triangle is approximately 8.5.
Based on the given answer choices, the correct answer is B. 8.5.
Answer
1:B; 8.5
2:A; 9.4
3:C; 1,1
4:A; -2
5:D; 4/3
6:B; 1
7;D; y= 2x-5
8:B; 30
9:C; y=9x+ 2/3
These are 100% correct so I hope it helps👍
