Question

Solve for x - 8.1 Geometry Quiz

Answer 1

Use the Pythagorean theorem. a^2 + b^2 = c^2 The 16.5 is c^2 because is not adjacent to the right angle and is the longest. So the problem is 9.2^2 + x^2 = 16.5^2. Once you square them you should get 84.64 + x^2 = 272.25. Then subtract 84.64 from 272.25 to get 187.61. Then you have x^2 = 187.61. Then you will need to get rid of the ^2 so square root both sides. Then you should get your answer of about 13.697. You should prob round this number though to the nearest 10th.

Answer 2

Answer:

x=13.7

Step-by-step explanation:

a^2+b^2=c^2

9.2^2+x^2=16.5^2

84.64+x^2=272.25    272.25-84.64=187.61

x^2=187.61

x=$\sqrt{187.61$

x=13.697080=13.7
