Answer:
-90 , 30
Step-by-step explanation:
sina = cos(2a)
= 1 - 2(sina)^2
2(sina)^2 + sina -- 1 = 0
( sina + 1 )( 2sina - 1 ) = 0
sina = -1 or sina = 1/2
=> a = -90 degrees or => a = 30 degrees
<span>The interior angles of any polygon always add up to a constant value, which depends only on the number of sides. We use the equation as follows:
</span>sum = 180 (n−2) degrees
sum = 180 (29 - 2) degrees
sum = 4860 degrees
Hope this answers the question. Have a nice day.
Answer:
C. x<18
Step-by-step explanation:
If you substituted the inequalities with 5, the logical one is x<18.
Especially since 5 is less than 18, it isn;t greater than or less than 2,9, or 42.
