x + -1.4 = 7.82
Reorder the terms:
-1.4 + x = 7.82
Solving
-1.4 + x = 7.82
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '1.4' to each side of the equation.
-1.4 + 1.4 + x = 7.82 + 1.4
Combine like terms: -1.4 + 1.4 = 0.0
0.0 + x = 7.82 + 1.4
x = 7.82 + 1.4
Combine like terms: 7.82 + 1.4 = 9.22
x = 9.22

Answer:
C
Step-by-step explanation:
Since Δ ABC is isosceles , then AB = AC and the base angles are congruent.
∠ ACB =
=
= 65°
∠ ACB and ∠ BCE are adjacent angles and are supplementary, thus
∠ BCE = 180° - 65° = 115° → C
