Answer:
The correct option is B. 252°
Step-by-step explanation:
There are 360° in the circle.
So using the relation :
⇒ arc ADC - arc AC = 2 × ∠ABC
⇒ arc ADC - 108° = 2 × 72°
⇒ arc ADC - 108° = 144°
⇒ arc ADC = 144° + 108°
⇒ arc ADC = 252°
So, The measure of ∠ADC = 252°
Hence, The correct option is B. 252°

cos 2x + 2 sin²x
= (1 - 2 sin²x) + 2 sin²x
= 1 - 2 sin²x + 2 sin²x
= 1
