Answer:
27
Step-by-step explanation:
2x+2=52
2x=50
x=25
x+2=27
The angle immediately below x makes up the third angle of the isosceles triangle whose base angles are 55°. That third angle and x are "vertical" angles, hence equal. The value of x can be found from the sum of angles of a triangle:
x + 55° + 55° = 180°
x = 70°
The appropriate choice is the 2nd one:
70°
I don’t that’s a question
