Step-by-step explanation:
3x+10°=70
or,3x=70-10
or,3x=60
or,x=60÷3
or,x=20

<u>Given</u><u> </u><u>Information</u><u> </u><u>:</u><u>-</u>
⠀
- A polygon with 10 sides ( Decagon )
⠀
<u>To</u><u> </u><u>Find</u><u> </u><u>:</u><u>-</u>
⠀
- The value of one of the exterior angles
⠀
<u>Formula</u><u> </u><u>Used</u><u> </u><u>:</u><u>-</u>
⠀

⠀
<u>Solution</u><u> </u><u>:</u><u>-</u>
⠀
Putting the given values, we get,
⠀

Thus, the value of the exterior angles of a Decagon is 36°.
⠀

-12 degree F + 19 + 19 + 19 = 49 degree F
I think the answer is 49 degree F...
