Answer:
x = 18
Step-by-step explanation:
The angle vertically opposite (5x + 2) is also (5x + 2), then
(5x + 2) and (5x - 2) are same- side interior angles and sum to 180° , that is
5x + 2 + 5x - 2 = 180
10x = 180 ( divide both sides by 10 )
x = 18
Answer:
What exactly is it asking to do?
Step-by-step explanation
The sum of all the angles of the triangle is 180°.
80 + 3x + x = 180°
80 + 4x = 180°
4x = 180 - 80
4x = 100
x = 100/ 4
x= 25
