Answer 2

Answer

∠ABC = 50º

∠ABD = 130º

Solution

Given,

$\sf\angle ABC = 2x + 10\degree$

$\sf\angle ABD= 8x - 30\degree$

Since ABC and ABD angle formed linear piar angle ,

$\sf\angle ABC + \angle ABD = 180\degree \\\\ \sf\implies 2x + 10\degree + 8x -30\degree = 180\degree \\\\ \sf\implies 10x = 180\degree +20\degree \\\\ \sf\implies x = 20\degree$

Thus , the angles are :

∠ABC =2×20º + 10º = 50º

∠ABD = 8×20º - 30º = 130º
