Question

Geometry: Help this makes no sense I don’t think there’s enough info needa find x so you have a triangle and you have a 90 degree angle and across that is the hypotenuse which is 18

Answer 1

9√2

Explanation:

a^2+b^2=c^2

a^2+b^2=18^2

a^2+b^2=324

324 ÷ 2 = 162

162 + 162 = 324 (on a 45 45 90 right triangle)

81 and 2 are factors of 162

square root of 162

√162 = √81 * 2 = 9√2
