Answer: 82°
Explanation:
To find the measure of angle A, we can use the fact that the sum of the angles in a quadrilateral is 360 degrees. Therefore:
A + B + C + D = 360
Substituting the given values, we get:
A + 149° + 86° + 43° = 360°
Combining like terms, we get:
A + 278° = 360°
Subtracting 278° from both sides, we get:
A = 82°
Therefore, angle A measures 82 degrees.
