So, here we have a hexagon. In geometry, there is a rule which says that the sum of all the angles inside a hexagon is equal to 720 degrees.
So, all we have to do is figure out the sum of the 5 angles we already have, and subtract that from 720.

112+133+128+100+120=593 (if I calculated that correctly)

So our angle ‘x’ would be 720-593, or 127 degrees.

frosja888 [35]

Answer:

1.) 138

2.) 55

Step-by-step explanation:

1.) 8 x 6 = 48 x 2 = 96

(middle) 8 x 3 = 24

(triangles) 6 x 3 = 18 divided by 2 = 9 x 2 = 18

96 + 24 + 18 = 138

2.) (middle) 5 x 5 = 25

(triangles) 5 x 3 = 15 divided by 2 = 7.5 x 4 = 30

30 + 25 = 55

Hope this helped!!

Step-by-step explanation:

$1.49 \times 0.0000001 = 0.000000149 = 1.49$

in this problem you also need to use scientific notation period to do scientific notation you need to go to the first non-zero digit after the decimal . and in this case that is one next thing you do is put the next numbers after the decimal that you just put in front of the one which is 49 in this case and that gives you your answer of 1.49

16.5 / p = 11 / 18

p = 16.5 × 18 / 11

p = ( 16.5 / 11 ) × 18

p = 1.5 × 18

p = 27
