Help pls haha also Merry Christmas

x = √39

General Formulas and Concepts:

Pre-Algebra

Order of Operations: BPEMDAS

Equality Properties

Trigonometry

Step-by-step explanation:

Step 1: Identify

Leg a = x

Leg b = 5

Hypotenuse c = 8

Step 2: Solve for x

√39

Step-by-step 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

i used to know how to do this in 7th but i forget easily
