A triangle has angle measures of 27°, 39°, and xº. Use the Triangle Sum Theorem to find the value of xº. O 66°
O 141
O 153
O 114°
what’s the answer?

114 degrees

Explanation:

Because when you add 27 and 39 together you get 66. And the interior of a triangle equals 180 so now you must subtract the 66 from 180. And once you do that you get 114 degrees.

they use tree rings to figure out weather patters.

d. new methods of assembly are introduced.

explanation:

this allows for the goods to be made on a larger scale. not faster because now it is shown to be made better, hence the greater productivity in the question. it is calling for something new to be introduced.
