Please help me answer this math question

Answer 1

Use the Pythagorean Theorm for right triangles where the squares of the two legs equal the square of the hypotenuse.
${a}^{2} + {b}^{2} = {c}^{2}$
Plug in the known leg and hypotenuse.
${15.3}^{2} + {b}^{2} = {35.6}^{2}$
Simplify by squaring.
$234.09 + {b}^{2} = 1267.36$
${b}^{2} = 1033.27$
Isolate b by square rooting both sides.
$b = 32.14$
The result is rounded
