All three angles of a triangle must equal 180 degrees, so you’d add the measures of angles BAC and ABC, which equals 86. Then you’d subtract 86 from 180 because you only have one angle left. So, your answer should be 94. Hope this helps!
Answer: x = 13
Step-by-step explanation:
Reorder the terms:
14 + 2x = 40
Solving
14 + 2x = 40
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-14' to each side of the equation.
14 + -14 + 2x = 40 + -14
Combine like terms: 14 + -14 = 0
0 + 2x = 40 + -14
2x = 40 + -14
Combine like terms: 40 + -14 = 26
2x = 26
Divide each side by '2'.
x = 13
Simplifying
x = 13
