Question

Help me, anyone???...​

Answer 1

Answer:

x = 34

Step-by-step explanation:

The 3 given angles form a straight angle and sum to 180°, hence

x + 12 + 100 + x = 180

2x + 112 = 180 ( subtract 112 from both sides )

2x = 68 ( divide both sides by 2 )

x = 34

Answer 2

Answer:

x=34

Step-by-step explanation:

Alright.

x+12+100+x=180

         2x+112=180

                2x=68

                   x=34
