Answer:

a. 75°

Explanation:

$m\angle A = m\angle C... (given)$

$(2x+15)\degree = (3x - 15)\degree$

2x+15 = 3x - 15

2x - 3x=-15-15

- x=-30

x=30

$\because m\angle A = (2x+15)\degree$

$\therefore m\angle A = (2* 30+15)\degree$

$\therefore m\angle A = (60+15)\degree$

$\therefore m\angle A = 75\degree$
