Answer 1

Answer:

hope the answer will help you

Answer 2

$In \: a \: triangle \: DEF, \\\angle D = 28\degree ,\\\angle F = 47 \degree$

$\angle E = \red { ? }$

/* By Angle Sum Property */

$\angle D + \angle E + \angle F = 180\degree$

$\implies 28 \degree + \angle E + 47 \degree = 180\degree$

$\implies 75 \degree + \angle E = 180\degree$

$\implies \angle E = 180\degree - 75\degree$

$\implies \angle E = 105 \degree$

Therefore.,

$\red { \angle E} \green { = 105 \degree}$
