Answer:
x = 23 degrees
Step-by-step explanation:
sin theta = opposite side/ hypotenuse
sin x= 9/23
Take the arcsin of each side
arcsin( sinx) = arcsin (9/23)
x = arcsin (9/23)
x=23.03568411
Rounding to the nearest degree
x = 23 degrees
Answer:
-7
Step-by-step explanation:
To find the common difference, you subtract a term from the term after it. For example, in the problem, you can subtract 13 from 6:
6 - 13 = -7
To check you can do the same thing with other consecutive numbers in the sequence like:
-1 - 6 = -7
since all of the sides are not equal, it is not a regular polygon.
a regular polygon is when all of the sides are equal, and the same with the angles.
hope this helps you!! <3
