Question

Can anyone help me solve this problem?

Answer 1

The answer is 8.9 units
4^2+8^2=x^2
80=x^2
8.9≈x

Answer 2

Hello There!!

Given

$\text{Base = 4} \\ \text{Perpendicular= 8}$

To Find

Hypotenuse of the triangle.

Assuming,

$\text{Perpendicular = ‘a’}$

$\text{Base = ‘b’}$

$\text{Hypotenuse= ‘c’}$

Solution

$\text{(c)² = (a)² + (b)²} \\ \\ \implies \text{ (c)² = (8)² + (4)²} \\ \\ \implies \text{(c)}^{2} = 64 + 16 \\ \\ \implies \text{(c)}^{2} = 80 \\ \\ \implies \text{(c)} = \sqrt{80} \\ \\ \implies\text{(c)} = 8.94$

$\text{Rounding it to the nearest tenth = 8.9}$

$\therefore \text{Hypotenuse of the triangle = 8.9}$

Option D= 8.9 units is the correct answer

Hope this helps!!
