In abc c is a right angle find the remaining sides and angles round your awners to the nearest tenth a=3 c=19

To find the answer, use pythagorean theorum (a^2 + b^2 = c^2)

We'll square a and c, and then subtract a from c.

9 + b^2 = 361

361 - 9 = 352

The square root of 352 is 18.7

18.7 should be the correct answer.
