Step-by-step explanation:

J = 2b

M = J + 7

M = 21

J = 21 - 7

J = 14

B = 7

<em>Equation:</em>

If M is J+7, so then J = 21-7. J is 2*b, so 2*b = 21-7. Then you subtract and divide.

Step-by-step explanation:

salut :

en utilisant le theorem de Pythagore on obtient :

AC²= AB² + BC²

(a+5)² = 7²+a²

a²+10a+25 = 49+a²

10a+25 =49

10a =24

donc : a = 24/10 = 12/5 = 2.4 unit
