Question

Please help I don’t understand what to do

Answer 1

18° 44'

Explanation:

43° 36' + 117 40'=

160° 76'

Since there are 60 minutes in a degree, it simplifies as:

161° 16'

To find the third angle, we have

180°-161° 16'

18° 44'

Answer 2

Explanation:

All of the interior angles of a triangle sum to 180 degrees

43 36' + 117 40' + x = 180

180 - 43 36' - 117 40' = 18 44'
