Question

16) given:DE is perpendicular to AB
angle B =40 degrees
angle DFA =110 DEGREES
FIND: x and y

Answer 1

Answer:

x=40 ,y =110 thank u thank you pls follow me

Answer 2

Answer:

x=50 degree and y=60 degree

Step-by-step explanation:

As DE is perpendicular to AB, so DEB is a right angle triangle

So by angle sum property of a triangle, x+40+90=180°

So, x= 50°

Now 110°+CFD=180(Linear pair)

CFD=70°

So, by angle sum property of a triangle

CFD+x+y=180

So,y=180-(50+70)

=60°
