Answer:
√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
Answer:
x = √39

- [Right Triangles Only] Pythagorean Theorem: a² + b² = c²
Step-by-step explanation:
<u>Step 1: Identify</u>
Leg <em>a</em> = <em>x</em>
Leg <em>b</em> = 5
Hypotenuse <em>c</em> = 8
<u>Step 2: Solve for </u><em><u>x</u></em>
- Substitute [PT]: x² + 5² = 8²
- Isolate <em>x</em> term: x² = 8² - 5²
- Exponents: x² = 64 - 25
- Subtract: x² = 39
- Isolate <em>x</em>: x = √39

now, we're assuming they're directly proportional, so say y = miles, x = hours.
