Step-by-step solution:
7x + 3 + 6x + 11 = 0
7x + 6x + 11 + 3 = 0
13x + 11 + 3 = 0
13x + 14 = 0
13x = 0 - 14
13x = -14
x = -14 / 13
x = -1.077 approx.

Answer:
1. ∠A and ∠B are right angles. Given
2. m∠A = m∠ B All right angles are congruent.
3. ∠BEC≅ ∠AED Vertical angles are congruent
4. ΔCBE ~ ΔDAE AA
Step-by-step explanation:
A proof always begins with the givens.
1. ∠A and ∠B are right angles. -------------->Given
2. m∠A = m∠ B are equal since-----------> All right angles are congruent.
3. ∠BEC≅ ∠AED are also equal since---->Vertical angles are congruent
4. ΔCBE ~ ΔDAE since two angles are equal----------> AA
