Work out the value of the missing angle x

The value of the missing angle, x° is 115°

Step-by-step explanation:

The sum of the interior angles in a polygon is given by the formula (n - 2)×180, where, 'n', is the number of sides in the polygon

The number of sides in the given polygon, n = 10 sides

Therefore;

The sum of the interior angles in the polygon is (10 - 2)×180 = 1440°

The given angles of the polygon are;

107°, 126°, 325°, 125°, 95°, x°, 90°, 280°, 47°, and 130°

Therefore, we have;

107° + 126° + 325° + 125° + 95° + x° + 90° + 280° + 47° + 130° = 1440°

x° = 1440° - (107° + 126° + 325° + 125° + 95° + 90° + 280° + 47° + 130°) = 115°

The value of the missing angle, x° = 115°.

question 1 is 8, question 2 is 9, question 3 is 24

step-by-step explanation:

now, the numbers they give you at the top are the key. from there, you just have to plug and chug! let's try 1, 2, and 3!

key: a=3, b=5, c=6

1. a+5

remember, a=3, so we plug that in to get 3+5=8

2. 15-c

c=6, so we plug that in to get 15-6=9

3. 4b

b=6, so we plug it in to get 4*6=24

time to try the rest on your own! if you put the answers below in a comment, i'll check them for you!
