Question

(math problem in picture)

Answer 1

Answer:

Answer D is correct

Step-by-step explanation:

You can use Pythagorean theorem to find this.

That means,

a² + b² = c²

here,

a ⇒ Side of right triangle

b ⇒ Side of right triangle

c ⇒ hypotenuse

Let us find now.

a² + b² = c²

a² + 4² = 8²

a² + 16 = 64

a² = 64 - 16

a² = 48

a = √48

a = 6.9 mm
