Answer:
Pythagorean Theorem Statement is below.
Therefore the value of x is 9 m.
Step-by-step explanation:
Given:
Label the vertices as A , B , C shown in figure below such that
∠A = 90°
AC = Longer leg = 12 m
AB = Shorter leg = x
BC = Hypotenuse = 15 m
To Find:
x = ?
Solution:
Pythagorean Theorem :
Pythagorean Theorem States that "the square of the length of the hypotenuse of a right triangle equals the sum of the squares of the lengths of the other two sides".
Which can be Written as

OR

i.e 
Substituting the values AB ,AC, BC we get

Therefore the value of x is 9 m.
Answer:
0.40
Step-by-step explanation:
5/13 = 0.38461538461. Hundreths place is the 2nd number after decimal so if you round 8 it'll be .40
the x s are the independent variable so any direct change to them is changing the independent. like the second one has -5 on the x
Step-by-step explanation:
a^2+b^2 = c^2
C is the biggest number, so put in all the numbers in the equation then if it's equal then it's a right triangle.
example: 6^2 + 8^2 = 10^2
36 + 64 = 100
100 = 100
this one is a right angle because the two sides is equal to the hypotenuse(largest number).
