The two legs of a right triangle are 20 and x - 8, and the hypotenuse is x. Find the length of the hypotenuse.

1 answer:

8 0

20^2 + (x-8)^2 = x^2

x^2 = 400 + x^2 -16x + 64

16x = 464

x = 29 = hypotenuse

Double - Check
29^2 = 20^2 + 21^2
841 = 400 + 441

Answer: 21.44 cm

Step-by-step explanation:

Given

Radius r=15 cm

distance of chord from the center is 10 cm

From the figure, the length of the chord is AC

Applying Pythagoras

$\Rightarrow AO^2=OB^2+AB^2\\\Rightarrow AB^2=15^2-10^2\\\Rightarrow AB^2=225-100=115\\\Rightarrow AB=\sqrt{115}=10.72\ cm$

The length of the chord is $AC=2AB=21.44\ cm$
