Answer:

a = 20.79cm ( 2 decimal places)

Step-by-step explanation:

find the length of the identical sides (i name it "x") first using Pythagoras theorem

$14.8^{2}$ = $x^{2} + x^{2}$

219.04 = $2x^{2}$

$x^{2}$ = 219.04/2 = 109.52

x = $\sqrt{109.52}$

now find a,

$a^{2}$ = $(\sqrt{109.52}) ^{2}$ + $(7.5 + \sqrt{109.52}) ^{2}$

$a^{2}$ = 109.52 + 322.7477 = 432.2677

a = $\sqrt{432.2677}$ = 20.791048
