Question

what is the measure of the missing angle

Answer 1

Answer:

The answer is 115 degrees

Step-by-step explanation:

You would need to find out the total of the angles in the triangle first (75+40=115) then subtract that by 180 (180-115=65) Take that and subtract it from 180 (180-65) giving you 115 for the outside line.

Answer 2

If you add the two angle we know witch are 75 and 40 which equals 115, and if every triangle has a total measurement of 180 degrees than we need to subtract 180 by 115 and get 65 degrees. The answer is 65 degrees.
