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°
3x < -6
x < -6/3
x < -2
Therefore, the solution set is {x | x < -2}.
Answer:
5 sides.
Step-by-step explanation:
Unlike a triangle, which is 180°, also equal to a straight line, the length is equal to 540°.
9 * 4 = 36 sooo 36 / 4 = 9
so the answer is 36 .
i hope this helps.
