The trigonometric identity states that the sum of the square of cosine and sin is equal to 1. In this case, the identity is tried to rearrange and tried to verify if the statement above is true.
<span>Square root 1 minus cosine squared theta = −sin Θ
This is only true in angles tried such as (360-45) or (270-45). hence </span><span> Θ should be in quadrant III and IV only</span>
Answer
Step-by-step explanation:
The diagonals of kite KLMN meet at 90°
Since, LK and KN are congruent, and form a set of opposite congruent angles. Congruent angles are equal.
All interior angles of a kite add up to 180°, therefore:-
Answer:
QS is congruent to NR because they are both the same length
Answer: -7 (30h - 11) / 4h
Step-by-step explanation:
Answer:
1600/49
Step-by-step explanation:
5 5/7 = 40/7
40/7 * 40/7 = 1600/49
