Answer:
Step-by-step explanation:
This is a right angled triangles and the summation of the other two angles must equal 90°
OR you can also say that the summation of all the angles in a ∆ must give us 180°
Therefore (2x+14) + (4x-26) = 90°
Expanding... By collecting all like terms, we have
2x+4x+14-26-90 = 0
6x - 102° = 0
Therefore, 6x = 102
x = 102/6
x = 17°

3 + (-9) = -6
The sum is negative.
