(math problem in picture)

Find the unknown side of the right triangle down below. round to the nearest tenth.

A. 7.2 mm

b. 8.2 mm

c. 5.4 mm

d. 6.9 mm

Answer 1

the answer of the question is b. 8.2 mm

Answer 2

Answer D is correct

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
