lft angle abd right angle equal..

hmmm

Step-by-step explanation:

sorry i dont know

Answer 2

Consider △ABC,

Then according to the given condition, ∠A=∠B+∠C

$\bold{Sum \: of \: all \: the \: interior \: angles \: of \: the \: triangle \: is 18 {0}^{0} }$

$\bold{Hence, ∠A+∠B+∠C=18 {0}^{0}}$

$\bold{2∠A=18 {0}^{0} }$

$\bold{⇒∠A=9 {0}^{0} }$
