Answer 2

Given:

Angle A=75°

Angle B=100°

To find:

Angle C-Angle D

Solution:

The required difference is 25°.

We can calculate the difference by obtaining the values of angles C and D.

Since ABCD is cyclic, angles A and C and angles B and D are supplementary.

So, angle A+angle C=180°

Using the values, we get

75°+angle C=180°

Angle C=180°-75°=105°

Similarly, angle B+angle D=180°.

100°+angle D=180°

Angle D=180°-100°

Angle D=80°

Now, the required difference=Angle C-angle D

=105°-80°

=25°

Therefore, the required difference is 25°.
