Answer 2

$\sf\angle ABD+\angle CBD=180° \: \: \: (linear \: pair)$

$\implies3x-13°+4x+11°=180°$

$\implies7x-2°=180°$

$\implies7x=180° + 2°$

$\implies x= \frac{182°} {7}$

$\therefore x= 26°$

$\purple{ \sf{now : }}$

$\sf\angle ABD = 3x-13°$

$\implies \sf\angle ABD = 3(26°)-13°$

$\implies \sf\angle ABD = 78°-13°$

$\boxed{ \orange{ \therefore\sf\angle ABD = 6 5°}}$

$\sf\angle CBD = 4x+11°$

$\implies \sf\angle CBD = 4(26°)+11°$

$\implies \sf\angle CBD = 104°+11°$

$\boxed{ \orange{ \therefore\sf\angle CBD = 11 5°}}$

HOPE IT HELPS!!
