Answer:

x = 50

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180°

Sum the 2 given angles in the lower triangle and subtract from 180 to find the third angle

third angle = 180° - (65 + 65)° = 180° - 130° = 50°

x = third angle = 50 ( vertical angles )

A triangle has to have three angles and they have to add up to 180 degrees so,

65+65=130

180-130=50

X=50 degrees because it is equal to the third angle.
