Answer

b=.75

Work Step by Step

The Pythagorean Theorem states that for a right triangle, $a^{2} +b^{2} = c^{2}$. Thus, we plug in the values given for a, b, or c, and then we use these values to find the missing value: $1^{2} + b^{2} = (5/4)^{2} \\\\ 1 + b^{2} =1.5625 \\\\ b^{2} =.5625 \\\\ b=.75$
