Question

Q4 find out what is the value of x y​

Answer 1

Answer:

we will know that sum of two interior angle be exterior angle;

BY USING THIS FORMULA

we will solve:

115° +y°=132°

So y°=(132-115)°

y°=17°

AGAIN!!

115°+y°=x°

SO

here we put the value of y°

115°+17°=x°

x°=132°

Answer 2

Answer:

=angleABC+angleABD=180°

=115°+X=180°

=X=180°-115°

=X=65°

=angleACE+angleACB=180°

=132°+y=180°

=y=180°-115°

=y=48°

Therefore,X=65° and y=48°
