Answer:
h=24
Step-by-step explanation: In order to solve this we have to apply the Pythagorean Therom which states a^2+b^2=c^2. c^2 being the the hypotenuse. First we have to plug in the values so the new equation is a^2+7^2=25^2. Now we simplify to get a^2+49=625. We can now subtract 49 from both sides to get a^2=576. The final step is to square it to get a=24. So h=24
Pr(1/2) for both I believe. If not right sorry.
Answer:
The demonstration is showed below
Step-by-step explanation:
The distance betwenn two points is given by:
If the point is equidistant from a point and a line, the distance must be equal. For the line let's select the point (x,-4), because the distance will be ortogonal, and is the small distance between a point and a line. So:
Removing the squares:
(x-2)² + y² = (y+4)²
(x-2)² + y² = y² + 8y + 16
y² - y² - 8y = 16 - (x-2)²
8y = (x-2)² - 16
y = (1/8)*(x-2)² - 16/8
y = (1/8)*(x-2)² - 2
