→ Substitute cos 2x and sin 2x by their expressions
→ Subtract both sides by sin x
→ Take sin x as a common factor in the right side
From the graph, the equation has 4 solutions, the intersection points between the 2 graphs
Cual es la formula de un octaedro
Answer:
B: m∠1 + m∠3 = m∠2
Step-by-step explanation:
The sum of a triangle is 180° so all of the angles in the triangle are equal to 180°. It is not possible for 2 of the angles in a triangle to be equal to the other angle in the triangle.
Hope This Helps :)
To answer this question you must know that there is a theorem called the "Two secants angle theorem", which establishes that the measure of an angle formed when two secants intersecting outside the circle is equal to 1/2 the difference of the two intercepted arcs.
Therefore, as you can see, the correct answer is the option B): B)<span>1/2 the difference of the intercepted arcs</span>
