Step-by-step explanation:
Based on the situation, it forms into a right triangle. So we will apply the Pythagorean Theorem here. The ladder acts as the hypotenuse while the height from the ground to the window serves as our side "a". We are tasked to solve for "b". Side "b" is the distance from foot of side a to the tip of side c which is the hypotenuse (ladder). We will derive the formula below to solve for b.
c = √( a² + b² )
c² = a² + b²
b² = c² - a²
b = √ ( c² - a² )
b = √ ( 13² - 12² )
b = 5 meters

Step-by-step explanation:
We need to determine the location of the gym considering that is located in the same distance with Ping and Ari's place. Such as to solve this, we have the solution below:
Ping place is 3rd street and 6th avenue which is (3,6)
Ari's place is 21's street and 18th avenue which is (21,18)
Solving the distance which is half way, we have
street midpoint = (3+ 21) / 2 = 12 streets
avenue midpoint = (6+18) / 2 = 12 avenue
The answer is 12th street and 12th avenue.
