Answer:
x = 6
Step-by-step explanation:
What we know:
* Values of angles 1 and 2, those being 54 and 83
* Sum of all angles of a triangle are = to 180
Process: Add 54 and 83
54 + 83 = 137
Subtract 137 from 180:
180 - 137 = 43
Solve for x:
7 x + 1 = 43
- 1 - 1
Subtract 1 from BOTH sides: 7x = 42
7x/7 = 42/7
Divide BOTH sides by 7 to isolate x variable: x = 6
Hope this helps and have a great rest of your day. Cheers!
