Answer 2

$\huge\bold{\gray{\sf{Answer:}}}$

Explanation:

ㅤㅤㅤㅤㅤ

∠DAC+∠BAC=180°(linear pair)

=>70°+x=180°

=>x=180°-70°=110°

$\huge\bold{\boxed{\purple{x=110°}}}$

Now,In∆ABC

=>∠A+∠B+∠C=180°(By angle sum property)

=>x+∠B+∠C=180°

=>110°+y+20°=180°

=>130°+y=180°

=>y=180°-130°=50°

$\huge\bold{\boxed{\purple{y=50°}}}$

What is linear pair ??

Linear pair means any two angles which are formed on a straight line and together makes the sum of 180° is called linear pair.

Note=>. Here ,only 2 angles makes the sum of 180°

What is angle sum property?

Angle sum property means in a triangle there are three angles formed and all three angles makes the sum of 180° then they satisfy the condition of angle sum property.

Note=>. Here ,3 angles makes 180°
