Answer 2

Step-by-step explanation:

Given: Figure

To find: Value of x°

Solution:

In ∆ABE

Sum of all interior angles are 180°,

thus,

Angle AEB=180°-65°-75°

Angle AEB =40°

We know that Vertical Opposite angles are equal.

Here

Angle AEB = Angle DEC

are Vertically opposite angles.

Thus,

Angle DEC =40°

In ∆ECD,again applying angle sum property of triangle

x°=180°-40°-110°

x°= 30°

Final answer:

x°= 30°
