Question

please answer question number 10​

Answer 1

Answer:

85°

Step-by-step explanation:

Given ∠ABC = 95°

ABCD is a cyclic quadrilateral since all its edges touch the circle.

Thus, the sum of the opposite angles will be 180°

∠ABC + ∠ADC = 180°

95° + ∠ ADC = 180°

∴ ∠ADC = 180° - 95°

Thus, ∠ADC = 85°

Answer 2

Answer:

<ADC = 85°

Step-by-step explanation:

•The sum of opposite angles of cyclic-quadrilateral is equal to 180°

So,

=> <ADC + <ABC =180°

=> <ADC + 95° =180°

=> <ADC = 85°
