Answer: 14 feet. a. The Pythagorean theorem is a^2 + b^2 = c^2, where a and b are the sides of a right angle. By plugging in the sides of the wall, and solving for c, you can find the answer. 10^2 + 10^2 = c^2
| 100 + 100 = c^2 | 200 = c^2 | c = sqrt 200 | c = 14. The other way to solve this would be using the trig functions. You know that the angle between the hypotenuse and the wall side is 45 degrees, so you can use Sine to determine the hypotenuse. Sine is equal to opposite over hypotenuse. Sin (45) = 10/h | Sin (45) * h = 10 | h = 10/Sin (45) | h = 14. Both of the methods result in 14.
Answer:
Step-by-step explanation:
m = 1/2, (18,10)
y - y = m(x-x)
y - 10 = 1/2 (x - 18)
y - 10 = 1/2x -9
y = 1/2x - 9 + 10
y = 1/2x + 1
Answer:
The needed expression is 
.
Step-by-step explanation:
Here the given expression is :
"the result of multiplying 1/2 by a number, then subtracting 9"
Let us assume the given number is p.
Firstly we multiply the given number p with (1/2).
Now, subtracting 9 from the result above, we get:
So here, if the number is p, then the result is :
Hence, the needed expression is .
