Given:
Measure of the internal angles of the regular polygon
To find:
The missing measure of angle x.
Solution:
The clear image of the question is attached below.
Number of sides (n) = 8
<u>Sum of interior angles of a regular polygon:</u>
Sum = (n - 2) × 180°
Substitute n = 8.
105° + 110° + 150° + 125° + 110° + 159° + 160° + x = (8 - 2) × 180°
919° + x = 6 × 180°
919° + x = 1080°
Subtract 919° from both sides.
919° + x - 919° = 1080° - 919°
x = 161°
The measure of the internal angle x is 161°.
The answer is 9 I hope I am not late to this question sorry if I am wrong,
Since a atom of chlorine has 36 fewer protons than an atom of iodine, then their total is 70.
So you have to subtract 36 from 70
70 - 36
= 34
*your answer is 34 protons for an atom of iodine
3449995000 is what I got, I did 3.45x10^9 and then used that number and subtracted the answer from 0.5x10^4 to get the final answer, if that makes any sense.
Answer:
9(6 - 4)
Step-by-step explanation:
9(6 - 4)
9 x 2 = 18
18 is your answer to the expression
hope this helps
hope this is right
