Question

find the lettered angles​

Answer 1

$\large☯ Answer ☯$

__________________________

❥ As we know,

∆ ABD = 180°

D = 90°

B = 60°

BAD = X

❥ ∆ ABD = BAD + ADB + DBA

180° = X + 90° + 60°

180° = X + 150°

180° - 150° = X

30° = X

❥ As we know,

∆ ADC = 180°

D = 90°

C = Y

DAC = 40°

❥ ∆ ADC = DAC + ACD + ADC

180° = 40° + Y + 90°

180° = 130° + Y

180° - 130° = Y

50° = Y
