Question

"Give your answers to 1 decimal place" help :(​

Answer 1

Answer:

$b$ ≈ $12.0$

Step-by-step explanation:

Using the Pythagorean theorem: $a^2+b^2=c^2$ where a and b are the legs and c is the hypotenuse.

$12^2+b^2=17^2\\144+b^2=289$

Subtract 144 from both sides

$b^2=145$

Square root both sides

$b=\sqrt{145}$

$b$ ≈ $12.0$

Answer 2

Answer:

Step-by-step explanation:

$12^{2} + b^{2} = 17^{2} \\144 + b^{2} = 289\\b^{2} =289-144\\b^{2} =145\\b=\sqrt{145} \\b = 12.04\\b = 12$

Hope it helps tell me if its right
