Answer:
1) x = 15
Step-by-step explanation:
We use the Pythagorean thm for these questions. Where a and b are the legs (So order doesn't matter), and where c is the hypotenuse
1)
a² + b² = c²
9² + 12² = x²
81 + 144 = x²
x² = 225
You square root each side so you can get rid of the exponent on x.
x = 15
Hello!
To find the distance between the points (1, 25) and (4, 21), you need to use the distance formula.
The distance formula is: . With the distance formula, you have to assign the ordered pairs before substituting them into the formula, which is also used to to find the slope of functions.
Therefore, the distance between the two points is 5 units.
