The value of x from the triangle is 12
How to determine the value
Given the sides as;
- Hypotenuse = 15
- opposite = x
- Adjacent = 9
Using the Pythagorean theorem
Hypotenuse square = opposite square + adjacent square
Substitute the value, we have;
15² = x ² + 9²²
Find the squares
225= x² + 81
collect like terms
225 - 81 = x²
144 = x²
Take the square root of both sides
x √144
x = 12
Thus, the value of x from the triangle is 12
