Find the measure of the sixth interior angle of a hexagon if the measure of the other five interior angles are 80°, 90°, 130°, 130°, and 150°. (Show
all work)

140°

Step-by-step explanation:

The sum of interior angles of a n-agon is (n - 2) * 180°

a hexagon should have the sum of angles equal to

4 * 180° = 720°

Now we know that the other five angles have total measure

80° + 90° + 130° + 130° + 150° = 580°

So the sixth one has to be:

720° - 580° = 140°

140°

Step-by-step explanation: required equation : 180*(n-2)

since it is a hexagon, the sum of all interior angles=180*(6-2)

                                                                                       =180*4 =720°

now the measure of 6th angle=720 -(80+90+130+130+150)

                                                    = 720 -580

                                                   = 140

hi,

i'm 75% sure the answer is 1,1 to both lines.

have a great day

the answer is: d) o, f, and kr.

atomic radius of bromine (br) is 114 pm.

atomic radius of oxygen (o) is 73 pm.

atomic radius of fluorine (f) is 72 pm.

atomic radius of krypron (kr) is 112 pm.

the atomic radius of a chemical element is a measure of the size of its atom.

the atomic radius varies with increasing atomic number, but usually increases because of increasing of number of electrons.

the atomic radius decreases across the periods because an increasing number of protons, because greater attraction between the protons and electrons.
