Answer:

see explanation

Step-by-step explanation:

Using the trigonometric identity

sin²x + cos²x = 1

Consider the left side

2cos²A - 1 ← replace 1 by sin²A + cos²A

= 2cos²A - ( sin²A + cos²A)

= 2cos²A - sin²A - cos²A

= cos²A - sin²A = right side ⇒ verified

Given the angles inscribed in the circle, find m ∠ DBC.

Cloud [144]

Answer:

m∠DBC = 51°

Step-by-step explanation:

Circle Theorem vocabulary

Chord: A straight line joining two points on the circle.
Inscribed angle: The angle formed when two chords meet at one point on a circle.
Intercepted arc: The arc that is between the endpoints of the chords that form the inscribed angle.

Inscribed Angle Theorem

The measure of an inscribed angle is half the measure of the intercepted arc.

Therefore:

$\sf \implies \angle DBC=\dfrac{1}{2}\:\overset{\frown}{BC}$

$\sf \implies \angle DBC=\dfrac{1}{2}\:(102^{\circ})$

$\sf \implies \angle DBC=51^{\circ}$
