Question

Answer please 3rd QUESTION Please​

Answer 1

Answer:

Solution:

y+130° = 180° (linear pair of angles )

=> y= 180°-130°

=> y=50°

In ∆CDE ,

x+y+40°= 180°

=> x+50° +40° = 180°

=> x= 180° -90°

=> x= 90°

Answer 2

Answer:

y=50 degree

x= 90 degree

Step-by-step explanation:

y =180- 130 (linear pair)

=50

x = 180-(50+40)

90

the triangles are not isosceles because the base angles are not equal
