Question

Help, i need help understanding it better.

Answer 1

Answer: 13

Step-by-step explanation: use pythagorean theorem which is a^2 + b^2 = c^2

so,

12^2 + 5^2 = c^2

144+25= sq. rt of 169= 13

Answer 2

x = 13

Explanation:

Given:

• Perpendicular = 5
• Base = 12
• Hypotenuse = x

To find:

• Value of x.

Solution:

We can find value of x using Pythagorean theorem.

The Pythagorean Theorem states that in a right triangle,the square of the hypotenuse is equal to the sum of the squares of the other two sides.

`\boxed{\boxed{\sf hypotenuse^2 = perpendicular^2 + base^2} }`

Substituting the given values into the equation, we get:

`\sf x^2 = 5^2 + 12^2`

`\sf x^2 = 25 + 144`

`\sf x^2 = 169`

`\sf x = √(169)`

`\sf x = 13`

The value of x is 13.
