Answer:

[tex]1) {a}^{2} = {39}^{2} - {15}^{2} \\ {a}^{2} = 1521 - 225 \\ {a }^{2} = 1296 \\ a = \sqrt{1296} = 36 \\ 2) {b}^{2} = {19}^{2} - {14}^{2} \\ {b}^{2} = 361 - 196 \\ {b}^{2} = 165 \\ b = \sqrt{165} = 12.8 \\ 3) {c}^{2} = {9.8}^{2} - {6.5}^{2} \\ {c}^{2} = 96.04 - 42.25 = 53.79 \\ 4) {d}^{2} = {24.7}^{2} - {14.5}^{2} \\ {d}^{2} = 610.09 - 210.25 \\ {d}^{2} = 399.84 \\ d = \sqrt{399.84} \\ d = 19.9[/tex]
