Answer:

√39

Explanation:

This triangle is a right triangle, we can use the Pythagoras Theorem.

The hypotenuse or the slanted part of the triangle is c, while the other two are b and a, doesn't matter the order.

In this picture we know what c is and what a (or b, doesn't matter, like I stated before ;w;) is.

a = 5

c = 8

b = x

a^2 + b^2 = c^2

5^2 + x^2 = 8^2

25 + x^2 = 64

x^2 = 64 - 25

x^2 = 39

√x^2 = √39

x = √39

  • [Right Triangles Only] Pythagorean Theorem: a² + b² = c²

Explanation:

Step 1: Identify

Leg a = x

Leg b = 5

Hypotenuse c = 8

Step 2: Solve for x

  1. Substitute [PT]: x² + 5² = 8²
  2. Isolate x term: x² = 8² - 5²
  3. Exponents: x² = 64 - 25
  4. Subtract: x² = 39
  5. Isolate x: x = √39
