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.
