4 + 2x = 12
-------------------------------------
Take away 4 from both sides:
-------------------------------------
2x = 8
-------------------------------------
Divide by 2 on both sides:
-------------------------------------
x = 4
-------------------------------------
Answer: x = 4
-------------------------------------
1, 3, 5, 7. 1 and 3 they are vertical meaning they are congruent. 3 and 5 are alternate interior angles meaning they are congruent. 7 and 5 are vertical so they are congruent.
1. 8.96 x 105 I think

Answer:
∠2 = 41°
Step-by-step explanation:
∠2 + 49° + 90° = 180°
∠2 + 139° = 180°
∠2 = 180° - 139°
∠2 = 41°
