Square root of 9 is 3 square root of 180 is 13.416roundes 3x13.416 is 40.248
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°
5 (the sides) x 0.8 = 4 meters
