Question
Easy
In a pentagon ABCDE, ∠A = (2x + 9°), ∠B = (2x + 1°), ∠C = (2x−1°), ∠D = (2x +5°) and ∠E = (2x-4°). Then, value of (2x + 10°) is :
1
124°
2
114°
3
116°
4
118°

Correct Answer
Option C
Explanation
To solve the problem, we need to determine the value of \(2x + 10^\circ\) given the angles of a pentagon ABCDE. The angles are given as follows: - \(\angle A = (2x + 9^\circ)\) - \(\angle B = (2x + 1^\circ)\) - \(\angle C = (2x - 1^\circ)\) - \(\angle D = (2x + 5^\circ)\) - \(\angle E = (2x - 4^\circ)\) The sum of the interior angles of a…Read More
