How to find value of y in polygon jklm

y = 22.5

Step-by-step explanation:

Here, the 4 angles shown are all exterior angles of the polygon.

The sum of the exterior angles of a polygon is ALWAYS 360°

So we add up the 4 angles (given in terms of y) and sum it to 360 and solve for y:

y = 22.5

step-by-step explanation:

no, her answer is not correct.   we square the lengths of all sides and then determine whether the pythagorean theorem holds here:

9² + 15² = 306.   this is not equal to the square of the longest side ( that square being 395.   answer c is correct.

hi there!

first we need to find out how much they are adding to each number to make the next number.

ex: 4 + 4 = 8, 8 + 8 = 16, and so on.

so continuing with 32,

32 + 32 = 64

64 + 64 = 128

128 + 128 = 256

256 + 256 = 512

4, 8, 16, 32, 64, 128, 256, 512

the 8th term of the sequence will be 512

hope this ! ~
