Question

Find the missing angle according to the Triangle Exterior Angle Theorem

Answer 1

Answer:

105 degrees!

Step-by-step explanation:

all the angles in a triangle must add to 180.

50+55= 105

therefore, the missing angle would be 75

x+75 must also add to 180 so the answer would be: 105 because 75+105= 180

Hope this helps!!

Answer 2

Answer:

x = 105 degrees

Step-by-step explanation:

First, figure out the interior angle, we can do this ading the two angles and then subtracting the sum from 180 (since the interior angle of a triangle adds up to 180 degrees)

180 - (55 + 50) = 75

next, we can figure out x by taking the sum (75) and subtracting that from 180 since it is a supplementary angle:

180 - 75 = 105

x = 105
