Answer

a=1.2

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: $a^{2} + 3.5^{2} =3.7^{2} \\\\ a^{2} +12.25=13.69 \\\\ a^{2} =1.44 \\\\ a=1.2$
