Answer:

The correct answer is first option √89

Explanation:

Points to remember

Pythagorean theorem

For a right triangle,

Base² + Height² = Hypotenuse²

To find the vale of x

From the figure we can see a right triangle,

Base = 8 units and height = 5 units

Hypotenuse² = Base² + Height²

x² = 8² + 5²

= 64 + 25

= 89

x = √89

The correct answer is first option √89

To solve this you must use Pythagorean theorem:


a^(2) +b^(2) =c^(2)

a and b are the legs (the sides that form a perpendicular/right angle)

c is the hypotenuse (the side opposite the right angle)

In this case...

a = 5

b = 8

c = x

^^^Plug these numbers into the theorem


5^(2) +8^(2) =x^(2)

simplify

25 + 64 =
x^(2)

89 =
x^(2)

To remove the square from x take the square root of both sides to get you...

√89 = x

(choice A)

Hope this helped!
