Answer:
∠ p ≈ 59°
Step-by-step explanation:
Using Pythagoras' identity in right triangle ABD to find DB
DB² = 5² + 6² = 25 + 36 = 61 ( take square root of both sides )
DB =
---------------------------------------
Using the cosine ratio in right triangle DBC
cos p = = = , thus
p = ( ) ≈ 59°
Try B...because the points meet at a intersection
