x=16
Step-by-step explanation:
Because this is an isosceles triangle the angle 2x+3 is the same as the missing angle. The angles in triangles add up to 180 degrees. 180-110=70.
Because the two angles are the same you can divide 70 by 2 to get 35.
35=2x+3.
35-3=2x+3-3
32=2x
32/2=2x/2
16=x
Ответ:
Then
2x+3+2x+3+110=180(sum of angles of triangle)
4x+6=180-110
4x+6=70
4x=70-6
4x=64
x=64/4
x=16
