Question

Need help 50 points.

Answer 1

15.58

Explanation:

The pythagreom therom states a^2 + b ^2 = c^2

9 + x = 18

81 + x = 243

then you would want to solve for x

243 - 81 = 243

then

√243 = 15.59

i hope this helps :)

Answer 2

`b\approx15.6 \ in`

Explanation:

We can use the Pythagorean Theorem to solve this question:

`a^2+b^2=c^2`

a and b are the legs of the triangle and c is the hypotenuse

Let's plug in the given values into the equation:

`9^2+b^2=18^2`

`81+b^2=324`

Subtract 81 from both sides

`b^2=243`

Take the square root of both sides

`b\approx15.6 \ in`
