Helppppppppppppppppppppp

Answer 1

Answer:

Step-by-step explanation:

Using the Pythagorean theorem:

c^2=a^2+b^2

15^2=10^2+x^2

√(225-100)=x

√125=x

Answer 2

This is a right triangle, so we can use the trusty Pythagorean Theorem to solve for the missing side.  Remember, the Pythagorean Theorem is a² + b² = c², where c is the hypotenuse of a right triangle.

The hypotenuse of our triangle is given, so:

a² + b² = c²

10² + b² = 15²

100 + b² = 225

b² = 125

b ≈ 11.2

Answer:

x is approximately 11.2 units.
